Question C3. Assume you are working in a design team and responsible to design a safe bearing supports, and you need to first analyse the angular motion of a mechanical rigid body system. Fig. 7 shows an equivalent mechanical system, in which, a homogenous disk of mass m = 4500 gm rotates at the constant rate w, of 145 rpm with respect to arm ABC, which is welded to a shaft DCE rotating at the constant rate w2 of 9.5 rad/s. Assume the mass of the bars ABC and DCE is negligible, and the important dimensions of the system are shown in Fig.7. Determine (a) the angular momentum of the disc about the point C (b) the couple of the body representing the dynamic reactions at the support points D and E, (c) Discuss the consequence of the unbalanced moment due to such motion and explain the ways to address the issue. disk r = 195 mm 210 mm B 210 mm 325 mm E 325 mm Fig. 7 (C3)
