    How To Calculate Forces Around This HInge?

    I am not a young student. I'm an old man with rotten physics and maths. My plan is to build a sheet metal folder. This kind of thing: Just like a hinge you lay the sheet metal on, across the hinge bit, and then close the hinge up which...

    What are the collision forces applied to the stops in a moving triple pendulum?

    Hello, it's been a while since I did not use lagrangian mechanics and all this stuff and would bet it's needed for my purpose. Introduction : if I take a simple pendulum and make it collide on its origin with a stop, how much will suffer the stop ? Knowing that the pendulum is subject to an...

    What precisely are "inertial" forces?

    This concept seems to be hanging me. It's used in a lot of D'Alembert problems and even on various texts on the web. The wiki page on "D'Alembert's principle" points to a page called "fictitious forces". Except the wiki page on this starts...

    Triangle of Forces

    So I am still a beginner in Physics and work asked me today to calculate if a 63mm Bore Pneumatic Ram will do the required job. Anyway, so I know how to calculate the weight capacity the ram can handle if it is at a 90 deg angle however if the ram is on an angle then I am stuck. I need to get...
