III. Consider the rigid bodies shown in Figure 1(b) below, which are identical and both in a horizontal plane. Rigid body (i) is pinned to the ground at its centre of mass G, under a moment M at point G. Rigid body (ii) is pinned at point O which is at a distance 2r from G, under a moment 4M at point 0. Assuming the radius of gyration around point G is equal to r, compare the angular accelerations of the rigid bodies and explain if one is bigger or if both [12 marks] are the same. 2r 4M Rigid body (ii) Figure 1(b) M Rigid body (i)
