Question 2. A uniform bar of mass m and length L is pivoted at point O, as shown in Figure 2 below. A point mass M is attached to the bar at a distance d from point O. Part I. The bar is released from rest from the position shown. Immediately after the release: (a) Draw the free-body-diagram showing all the forces acting on the bar. (b) Obtain an expression for the angular acceleration of the bar in terms of m, M, L, d, g, and 8 (g is the acceleration due to gravity) in the fixed frame A (in terms of a unit vector). (c) Find the magnitude of d for which the angular acceleration maximises. Briefly explain the reasoning for your choice [6 marks] [13 marks] [5 marks]
