Figure 4 (a) shows a thin circular disc with a mass of 2 kgwelded to the surface of a thin square plate with mass of 1 kg andlength of the edge, l = 0.X m, where X is 1.The disc is pin join tothe yellow bracket at the centre of the disc and is free to rotate.Both disc and plate are homogenous solids.
(i) Give the equations for mass moment of inertia for thincircular disc and thin plate. Then, give the parallel axistheorem.
(ii) Determine the angular acceleration at this instant if aForce, F = 0.X N, where X is 1. F is directed towards the centre ofthe square plate. The system is initially at rest.
