|Problem # p044|
The homogeneous semi-circular disk of mass m and radius R
is released from rest in the position shown. The center of mass of the
semi-circular disk is at cm and the mass moment of inertia with respect
to its own center of mass, , is given by the
equation below the figure.
Due to friction at point A, where the disk and the supporting floor touch, no slipping is observed as the disk begins to roll. The ultimate goal of this problem is to determine the necessary coefficient of friction and the initial acceleration.
Please, answer the questions below, they and the included hints will guide you through the problem.
