A uniform steel rod has length of 1.8 m, density of 7.9x109 kg/m², and ring cross-section of 45- mm inner radius and 50-mm outer radius. It is at rest on a frictionless surface when a horizontal force of 1 kN is applied at point C, as shown in Figure 2. A 0.6 m 1 kN G 50 mm 1.2 m 45 mm B Figure 2 (a) Determine the acceleration of the centre of mass G, and the angular acceleration of the rod. (9 marks) (b) Determine the accelerations of points A, B, and C. (7 marks) (c) Someone claims that stress is generated in the rod due to the inertial force for dynamic equilibrium. Do you agree? If no, show the reason; if yes, determine and sketch the inertial force on the rod. (5 marks) (d) Someone claims that if the 1-kN horizontal force is maintained at C, the angular acceleration of the rod will be a constant. Do you agree? Justify your answer. (4 marks)
