Figure 4 (a) shows a thin circular disc with a mass of 2 kg welded to the surface of a thin square plate with mass of 1 kg and length of the edge, l=0.Xm, where X is the last non-zero digit of your Matric number. For example: if your matric number is AN201050, then l=0.5 m. The disc is pin join to the 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 thin circular disc and thin plate. Then, give the parallel axis theorem. (5 marks) (ii) Determine the angular acceleration at this instant if a Force, F=0.XN, where X is the last non-zero digit of your Matric number. For example: if your matric number is AN201050, then F=0.5 N.F is directed towards the centre of the square plate. The system is initially at rest. (16 marks) Explain and then sketch the free body diagram and kinetic diagram of ONE (1) example that must be treated as a rigid body that you can find in your house. (4 marks)
