1 X 2. Question 2 [18] A uniform rigid bar with a mass of m = 12 kg is pivoted at point O as shown in Figure 2.1. The bar is connected to two springs with a stiffness k1 = 4000 N/m and k2 = 2500 N/m and also a mass of M = 60 kg is attached at the end of the rod. The system is subjected to a static force f(t) = 500 sin 104t at the end of the rigid bar. Considering a small angular displacement of of the rigid bar about the point O, then, 2.1.
