are there some general formulas for each of the cases - no matter if it is zero-or non-zero work?

Thank you for your fast reply Mapes! To complicate maters - the surface is rubber and steel for the cylinder. So there is quite a bit of deformation done to the rubber while rolling / sliding / torsion. The force for rolling, measured in the axis, is significantly lower than in sliding. I...

Energy "lost" in rolling, sliding and torsion Hey everybody, I have a question concerning three states and the state of energy in them. 1. Rolling 2. Sliding 3. Torsion For example: If I have a steel cylinder with diameter d on an axis (no friction in the axis) rolling horizontally over a...
