D B 6 in. A 2 in. At the instant shown the 6 lb. circular disc, with radius of gyration k = 1.75 in, is rotating with an angular velocity 200 rpm counter-clockwise about a stationary pin at its center A. The 2 lb. uniform rod BD is of length 10 in. and is rotating with an angular velacity 40 rpm counterclockwise and 30 (a) Draw the FBDs of the disc and the rod (b) Write 3 equilibrium equations for each FBD = (c) Write down a set of kinematic constraints that need to be satisfied. Note: All equations in (b&c) should be in terms of the unknown reactions in the FBD in (a), acceleration at a suitable starting point and angular acceleration of each rigid body (DO NOT SOLVE THE RESULTING SYSTEM OF EQUATIONS)
