Heat generation

Hi,

I am testing or trying to figure out how much heat would be generated for a piston that moves up and down and has two semi-circle wedges that press against to slow down its motion.
I want know what factors and equations I can use to calculate the heat generation?
All other related topics seem to be about rotating disc.

Thanks,

You haven't really given enough information to give much of a reply, but the heat generated by friction is equal to the Force times the Distance moved.

The piston is only moving along one plane....ie vertically. The clamps are situated around the middle and squeeze against the piston as it moves up and down acting as a damper. Does that help?

Not really, but as said, if you have a force and a distance, you can calculate it.

Well, you'll need more than just a force and distance I think. I believe that you'll need the normal force acting on the piston from the "clamps". Even from there, you'll need a friction coefficient.
