Re: Physics Quiz 2

I like where this is headed.

FYI: In order for the weight to interact with the ground under the wheel and not via a reaction at the "frictionless pivot" (assumed to be a revolute joint) it must instead be a cylindrical joint. Otherwise the normal force is indeterminate (as it can have any pre-load or none at all).
