Application of mechanics to the study of static equilibrium of rigid and elastic bodies. Topics includes composition and resolution of forces; moments and couples; equivalent force systems; free-body ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...
