1. which a disk A of radius r rotates about a fixed vertical axis with angular displacement q1. A bar B of length h is pinned to A such that the axis of rotation is a radial line of A. (Note this is a different pinning between disk and bar than you considered in the first exam). Let q2 designate the angular displacement of B relative to the vertical as shown. Let us consider the case in which both A and B are massless, but the particle P at the end of B has mass m. 
2. 
   
3. Determine equations that govern the motion of this system. Define generalized speeds u1 = ˙q1 and u2 = ˙q2. 
4. 
   
5. Determine both the kinematical differential equations and the dynamical differential equations.
