Hi rb1957
I did it graphically, I assumed a torque on link(A) and knowing that the force in link(C) has to be parallel to the link I calculated the force on link(C) at the intersection of the links (A)& (C). Now the force at both ends of link (C) must be opposite and equal and so from that...
Hi rb1957
Thanks for your positive comment.
I had a go at solving the posters problem by finding the parallel force in the two bar link and then just using that force to obtain the torque about the longest link.
My estimate for percentage torque output was around 1.28 so very similar to the...
Hi
Here is a link to a similar problem to yours, the only difference is that they apply an external force to hold the mechanism in place and assuming you know the torque to the driver lever you can apply the same methodology.

Hi Everyone
Thanks for all your help, I will rest easy😀👍.
Tomfh, I have no idea when it appeared, I only noticed it today when I was leaving the house, it looked at first like someone had drawn a black line with a biro pen.

Hi franhd
Any chance you can provide a sketch of the configuration?

Hi PhamENG
Yes I will make sure I have my eye on the mortar 👍

Hi all
I found it odd that the mortar around the brick appears in tact and I also wondered whether it’s been there all the time and I only just noticed. Certainly could be due humidity changes.

Hi KootK
Thank you for your response it’s appreciated 😀👍

Afternoon All
I don’t very often ask for help however I would welcome any advice on the brickwork on my home.
I have never noticed this small crack in the brickwork until today. The house is around 40years old and I have had no problems over the past years.
The crack (see photo) appears to be...
Right I’m going to guess that the orange coloured lines on the diagram is the catch that the OP refers too and that at the 2000lb the beam shortens sufficiently in the axial length to release it from its catch and the load runs off the beam, maybe a diagram with some labels on it and a proper...
Hi Mr Curious
I think I understand what you are trying to do, however I don’t think it will work based on the assumption that the threaded hole is machined over the groove and is tapped into both side walls? So from the info you have posted the screw thread runs parallel to the groove walls so...
Hi amarks
Just having a Quick Look at your calcs and they seem okay to me. I will study it in more detail and shout up if I see anything. Thanks for the update 👍

Hi amarks
Can you provide details of your shaft you are trying to size, giving us a blank formula and saying it appears to give a much larger shaft than expected doesn’t give us any information to help you.

Hi icebloom
I don’t know of any papers but there may well be some.
My limited understanding is that if you weld or subject an 8.8 bolt to very high heat, then it loses its high strength so an 8.8 bolt has a minimum yield of 640Mpa in its off the shelf state but once it’s been subjected to high...
Hi joccob
I have amended my post 25h August regarding the number of surfaces, my statement was incorrect.
“Do not worry about your problems with mathematics, I assure you mine are far greater.” Albert Einstein
Well that’s interesting however I am not sure that the static laws of friction apply to paper sheet because after the first test with one friction plane any static charge would affect the next experiment.
For the experiment to happen as it did on the video then the coefficient of friction must...
Hi Joccob
There is nothing wrong with your workings out, if you look at the third line of the equations you have written on the right hand side of your post you state Fpull = 2μFn, which aligns with what others and I have said, if you double the normal or applied force you double the pull force...
