Title: Could Madeleine have slid open the unlocked patio door?
Post by: sadie on April 22, 2018, 08:42:57 PM
Even if the door wasn't latched she would still need her fingers to push or pull it.  How do you think she managed it ... did she blow on it?  @)(++(*

Unless it was a very Rolls Royce sort of window (and the place does not look Rolls Royce at all), and the patio slid open very easily, I am very doubtful that she could manage to open the patio door at all let alone close it and manage all the near impossible obstacles ahead.

Why wouldn't she have shouted her Mum and Dad , she surely could see and hear them * if * she managed that door .... and they would hear her too.  Parents hear the distressed cry of their children over everything else.  The group would see her, imo

IMO, you are all barking up the wrong tree.

I tried a sliding door last week.... Pulling as an adult horizontally it was not difficult  to open.... Reaching up as a child would have to it was impossible IMO

lets say a force applied in a horizontal direction has a value x....then the same force applied at an angle has a value x times the cosine of the angle but also produces a downward force x times sine of the angle which causes a substantial increase in friction...but im sure you understood all this already

Open a sliding door with your elbow at the same height as the handle..
Then try with your elbow in a vertical line to the handle

Why is that relevant? Average height 4 yo girl is about 105 cm. Handle should be between 90cm and 100cm a fairly straight pull. In fact a lot straighter than for an adult.

No... A child would have to have their elbow at head height or above to apply a horizontal force... Not possible. Imo... Much more likely to reach up with a, straight arm

You have mashed up a horizontal with a hypoteneuse of the same length, but hey-ho.

Quite why you think an adult applies a horizontal force eludes me.

Quite why you think Madeleine applied a downward  force also eludes me.

And your emulation fails to answer whether Madeleine could or could not open the patio door.

I seem to remember one explanation of the unlocked patio door was so that Madeleine could get out if need be.  If so, trigonometry does not enter the equation.

Well look at small girls nearly 4 and see if they can open a sliding door.  I know some could be full of sand and dirt and become difficult to open.  So we may never know for certain.

i havent mixed up anything...with respect dont apply for  a job teaching maths.....
the downward force is  a component of a force directed below the horizontal...I could expalin but you may not follow the maths..

As the door wasn't closed there was no need to reach up to a handle. All the child had to do was put their hand into the gap on the far right and push to their left.

It was pointless checking for Madeleine's fingerprints on the doors as she occupied the apartment. Finding her fingerprints on the front door or the patio door was not significant.
I beg to differ. 
If Madeleines fingerprints had been found in the correct position for opening and closing doors, windows etc. then it would have been evidence that she had wandered out herself


Now the window was open.  People who think that she wandered out have a question to ask themselves.

Had Madeleine  opened the window and shutters, she would have left fingerprints.  But despite the PJ checking the window and shutters for fingerprints, none of Madeleines were found.   Madeleine obviously did not open the window and shutter.  Yet some of you believe that Madeleine walked out. 
Who opened the shutter and windows then?  An abductor


IMO, it could only have been an abductor wearing gloves who opened that window.

Post by: sadie on April 23, 2018, 12:02:23 AM
I'm trying to think how they would have got a reference sample of Madeleine's fingerprints in the first place.  If small fingerprints were found they could be attributed to a child but who?
From her suitcase maybe?   Or bedroom at home.

But a good point made there

Thank you for concretely confirming what I have been banging on about. 
No small or medium child would have opened our old patio door. 
The new one is so much better .... but I still doubt that a tiny tot like Madeleine could open it, having to exert the push or pull at above head level.  Ergonomically that would be so difficult for a tiny tot having to exert the force so high up.  IMO

And again... I bent my knees and elbow

Also you carry more weight and also are stronger, both of which produce the necessary force that I doubt Madeleine had.

Madeleine was reported as being 90 cm tall.  You should try pulling something horizontally that is well above your head, slarti

BTW, you, of all people with your technical know-how, should understand and back what Davel is saying.  IMHO

Why aren't you?  Does it spoil your agenda maybe?

Sil, what are you on about.

You obviously do not understand the Mathematics of it.  I understand the priciples of it and used to use it often.... altho I have forgotten the Mathematical side of it now.

Of course her pull will be affected by her height, her weight and stength.

..... and With Madeleine being shorter, there will be a vertical component to the thrust, which will reduce the horizontal thrust and also tend to jam the  patio door as it slides, as it pulls the one corner of the sliding window down.

Most handles are a metre (100 cm) high.  With Madeleine being only 90 cm according to her Mum, the opening handle/grip will be 10 cm ABOVE the TOP of her head.  That would make the pulling or pushing process very very hard and probably impossible for Madeleine


Suggest that you do what Davel did, or sit on a low stool and try it yourself with your hands as high above your head.  Then see how you get on relative to opening the door from a standing position

Then compare your weight and strength to those of Madeleine.  Putting the two components together, I bet there wouldn't be much horizontal thrust left

Citing an advert on Amazon to prove a point is no match for actually being in the apartment and drawing one’s own conclusions by looking at the actual door, how it operates etc.  The police did not seem to give the idea of Madeleine exiting via the patio door much credence, you’d have to wonder why.

People are hypothesising about a child not being able to open a door without any knowledge of the actual door. Have you pointed that out to them? Very young children are able to open this type of door, and that's a fact.

You should have wrapped this in an IYO, because that is what most of this is.

Davel was using simple trigonometry re right-angle triangles - SOH - CAH - TOA. I learned that about age 14.

I know what Kate and Gerry said about Madeleine's height.  IMO they got it wrong.

It's trigonometry. Right-angled triangles. Learnt at age 14.

If it is used in A-level Mechanics, so what?  The clue is in 'applied' Maths.  I was probably using it in applied maths at university, but that hardly makes it university level.

To use your own words "So you have got it wrong."

People are hypothesising about a child not being able to open a door without any knowledge of the actual door. Have you pointed that out to them? Very young children are able to open this type of door, and that's a fact.

 Last night my 21 month old son showed me (proudly) that he could not only unlock, but open our sliding glass door. Does anyone know of an extra lock that I can use to put on it?

I have seen Davvel acknowledge on this thread that we don’t know whether or not Madeleine could open the door, and the fact that the police put woke and wandered as the least probable scenario tends to suggest that it’s unlikely in their view, them being in full possession of the necessary info to come to a conclusion (and I doubt they needed to consult Amazon either).

We don't know any of that (friction), so if by chance it was a very easily moved door, we can't say for certain it could not be done.
With sand about it is likely it would have lots of friction, especially in the ground runners .... it is also fairly old, has been used by 'often couldn't care less' changing guests.  And judging by images of various windows and doors wasn't terribly high spec to begin with.

I repeat: weighing everything up, including the mechanical disadvantages caused by Madeleines lack of height, body weight etc. + potential friction I am extremely doubtful that she could have done it.

I believe Kate and Gerry, they think that that Madeleine couldn't have managed it

You should have wrapped this in an IYO, because that is what most of this is.

Davel was using simple trigonometry re right-angle triangles - SOH - CAH - TOA. I learned that about age 14.

I know what Kate and Gerry said about Madeleine's height.  IMO they got it wrong.
All facts Sil, so IMO NOT necessary.

Yep we all did sines, cosines and tangents at about 14.  And some of us used them since at a more advanced level involving forces etc.

IYO, Kate and Gerry got their daughters height wrong?  So YOU, who has never met Madeleine KNOW her height better than they did?

I am merely pointing out, in answer to those who are trying to make a case that Madeleine couldn't have opened the door, that other children can and do. In Madeleine's case she didn't need to reach any handle because the door was slightly open. This child, who was definitely younger than Madeleine, had no trouble reaching the patio door handle.

Why would it be? Except in the context of at what age one would one learn about the resolution of forces, triangle of forces call it what you will which is what you seem to be having a p*****g contest with SiL over.
During the 1950s it was "O" Level Physics. Today it is GCSE Physics. Certainly the basic principles are taught before "A" level.

If the door handle was in the centre as per the photo opening the door was more a push than a pull.  I'm sure a human can push a greater weight than they can pull.
"When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So it is easy to pull than push an object."  That is applying to an object lower than the shoulders so is that effect reversed when the handle is higher than the shoulder?

It looks like there's a handle in the middle in 5A (a bit small to see clearly). However, if it was slightly ajar, she could, in theory, have pulled it open from lower down.

B - Pages 967-972 Processo vol 4.
At 11:00am on 4 May 2007 I, IT, assistant-specialist, began to examine the following location:
At apartment 5A, Ocean Club:

- Side of the patio door: One adequate print recovered but not matched to known persons.

- Outside of one patio door: Eight inadequate prints were recovered.- Outside of [the other] patio door: One inadequate print was recovered.- Outside of the external blinds to the children's bedroom: three inadequate prints were recovered.

http://www.mccannpjfiles.co.uk/PJ/FINGERPRINTS.htm#p4p967

I'd have thought she'd have left prints on the inside while trying to get it open, but the only identifiable print on the side, after a mega search via Interpol, turned out to belong to a GNR officer.

I haven't found anything about prints on the inside, but it's not clear if they checked and didn't find any, or whether they didn't check the inside... so dunno.

Even if she did manage to get out, she would have had to think to close it again and open / close the two gates.

We all know that kids can get up to all sorts of surprising things, but I just find it unlikely that a sleepy child, not quite four years old would do all of that.

As an artist, specializing on figure drawing I can see from her body proportions, that child looks considerably older than Madeleine. 

The handle is in line with her nose NOT 10 clear centimetres above her head, as with Madeleine  That girl is approx 20 cm taller than Madeleine

... And even she is using two hands.  Did she manage to open it ?

Davel had stated that he cant find the evidence that Kate said that Madeleine was 90cm tall .  It probabl;y has been wiped now from the forum and internet, but it has been posted at least twice here ... and i can confirm seeing the same info


This thread is in a mess.  Some posts are from the previous thread and when you answer them on this thread, the post comes up on the earlier thread.

If it is used in A-level Mechanics, so what?  The clue is in 'applied' Maths.  I was probably using it in applied maths at university, but that hardly makes it university level.

To use your own words "So you have got it wrong."

Do you ever post without childish sniping?  It is sooooooooooo boring.  IMO of course.
Davel is correct Sil

You very obviously haven't gone beyond the simple Trigonometry ... and are not aware of its use at higher levels.

I see that Davels post showing the Maths and Mechanics has been removed and I wonder why?

That post was an important post, but it has gone 8)-)))  %56&

Why?

It doesn't matter how old or how tall a child is, if a door is open all they have to do is crawl out.
Err, Yep  @)(++(*

But we are talking about the ability of Madeleine to open a door where the handle is 10 cm above the top of her head, Angelo.  Not whether she could walk out or crawl out of an already open door.

Davel and I, both having studied applied Maths and applied Mechanics at an advanced level, maintain that she would be unable to provide the forces necessary.  I have forgotten so much of the Maths now, but remember the principles. 

I taught Maths at secondary school for a while, but apart from the principles it has virtually gone mow

That's just it, we only have Kate's say-so as to what she found at 10pm.

IMO, We should not be dismissing Kates evidence, because we now know that Amaral got it all wrong about the dogs alerts. 

There is NO evidence against either of the Mccanns, and SY and the Porto Special group have confirmed that they are NOT suspects

How do you know that identical forces are required to open the two diffent doors ?
Did you time travel with a force gauge?
Why aren't YOU supporting Davel, Alice?

With your Mechanical training and expertise, YOU KNOW what he is saying is correct.

I didn't need to be there, Sadie, all I needed to do was read the files where the evidence can be found.

Because this latter access is most convenient, it being closest to the restaurant entrance, the lounge door stayed closed but not locked in a way that it could be opened from the outside, permitting there to be a gap in which to introduce a hand {i.e. the reporter says that the door would be ajar}.

As an artist, specializing on figure drawing I can see from her body proportions, that child looks considerably older than Madeleine. 

The handle is in line with her nose NOT 10 clear centimetres above her head, as with Madeleine  That girl is approx 20 cm taller than Madeleine

... And even she is using two hands.  Did she manage to open it ?


TBH, Gunit, you are wasting your time, because altho many on here [say] they dont understand the mechanical disadvantages, SY and Porto special Madeleine group will have experts to advise them.  Both Alice and slarti should know what they are talking about, but prefer it seems to keep quiet.

Door handles on sliding doors are typically placed between 90cm and 100cm which makes the child between 90cm and 100cm a fairly normal height for a 4 year old.

Davel had stated that he cant find the evidence that Kate said that Madeleine was 90cm tall .  It probabl;y has been wiped now from the forum and internet, but it has been posted at least twice here ... and i can confirm seeing the same info


This thread is in a mess.  Some posts are from the previous thread and when you answer them on this thread, the post comes up on the earlier thread.

Why were they split?  They were fine before, IMO ... and now they are in amess.  I have just wasted well over an hour answering posts to find that some of the answers are elsewhere.

I am truly annoyed.

So no cite then?

We don’t dismiss Kate’s evidence, it just can’t be relied on as a sole indicator of fact in any court case that may happen.

Possibly my post got wiped, but I have gone beyond age 14 trigonometry, at A level and university level.

It's still simple trigonometry.

Have you ever even looked at the PJ Files Sadie? I would have expected anyone with basic knowledge of the case to know who 'that child' is. She is definitely younger than Madeleine and if she is 20 cm taller then Madeleine was indeed small for her age.

GMcC is opening the patio door; it is not ultra smooth, but the door moves easily.

IMO a 4 year old would be able to open the patio door.

Where do you think the PJ came by this information: "permitting there to be a gap in which to introduce a hand"?

This report was based upon a timeline analysis (the result of statements made to the PJ and to Control Risk by 5 elements of the T9, by the client support service staff from Mark Warner and from other statements, a text having been compiled for an English analyst) and various chronogrammes of communications elaborated and presented to the British police who were in Portugal in cooperation with the PJ.

Well does that make it a fact then?  Fact: "The patio door was left with a small gap so it can be opened from the outside".

There is no handle on the outside AFAIK, so it would be helpful to leave a small gap to facilitate opening the patio door from the outside.

Would a child of four close it after them?   I think not.   Neither do I think a child of four would climb over a gate at the top of steps in the dark.  IMO

It seems to me that Madeleine could have slid open the unlocked patio door. Whether she did is another question altogether.

She could have closed the door behind her in order to protect her siblings.  As you say, it is a possibility in the midst of other possibilities.  At the end of the day it is the hard evidence which counts and not what witnesses claim to have done or seen because witnesses in such a situation are unreliable.

Until witness statements are checked and co-ordinated each one is only a small part of the whole as seen from one point of view.  In my opinion it takes a competent investigation taking in the overall picture to work out what might have happened.
As we know the PJ in the final report concluded that the woke and wandered scenario was the least likely to have happened ... they must have had their reasons for determining that.

" they must have had their reasons for determining that."  Could be true but until we see the whole picture we don't understand what is going on. 
They have never given their reasons for that conclusion.
