    1. Homework Statement This is a relatively simple problem in classical mechanics, but my attempt at a solution seems to conflict with the result my teacher announced. The problem is as follows: A homogeneous cylinder with mass M and radius R lies at rest on a plank. The plank is then...

    Is this a meaningless problem formulation?

    A car is driving along a curved path (with a given radius) that is angled relative to the surface of the earth. The speed is of such magnitude that the friction force between car and road has a component directed downward the incline, however the friction does not have its maximum value. (So...
