The angle ##\psi## is the angle the gas spring makes with the horizontal, on the left hand side, ie the angle ##S \widehat{P} Q##. The equilibrium formula relates ##F_s, F_l, D, F_g## in terms of the parameters ##a, b, c, \theta##, and ##\psi##. However it might be more convenient to eliminate...

The force of atmospheric pressure, like so many other concepts in physics, greatly challenges our common sense notions. One of the early investigations into this force was the Magdeburg Hemispheres experiment in the 1600's (see Wikipedia) where teams of horses could not pull apart two copper...

Thanks Tazerfish, appreciate your comment. I use Tikz for diagramming which is a fantastic tool. The gas spring is an interesting problem and a good exercise to work through. The maths is fun, but I just wanted to quote the end result, though I could supply a derivation if anyone was interested...

Hi, I have just joined this forum. I am an independent learner in Mathematics and Physics, and hold a batchelor's degree in Mathematics, and have formerly worked as a software developer. I have over past couple of years been re-teaching myself Maths/Physics, greatly assisted by the wonderful...

You should check out some of the specialized gas spring shops online and their calculation tools. These design your gas spring for you, producing the extended/closed lengths, force rating, and mounting positions, and some have simulators showing the hand force needed to operate the lid...
