Comparative Vertebrate Anatomy
... There are several ways to represent this mechanically. Perhaps the most intuitive representation is with torques and levers. The balance of forces about a point of pivot (fulcrum) depends on the forces, multiplied by their lever arms (lo or li), the perpendicular distance to this point of pivot. Thi ...

Newton`s 2nd Law
... More interesting still, friction does not depend on the area of contact. Slide the crate on its smallest surface and all you do is concentrate the same weight on a smaller area with the result that the friction is the same. So those extra-wide tires you see on some cars provide no more friction than ...
