Given : A thin, homogeneous bar having a mass of M and length L is pinned to ground at its mass center G. Particle B, having a mass of m, is rigidly attached to the right end of the bar. A spring, having a stiffness of k, is attached between end A of the bar and pin C on a wall. The pin G is a distance of b from the wall. When the bar is horizontal (Position 1 shown below), the spring is unstretched.
Find: If the bar is released from rest in Position 1 above, find the angular velocity of the bar in Position 2 when the bar is in a vertical position. Use the following parameters in your analysis: M - 15 kg, m - 25 kg, k - 100 N/m, L - 3 m and b - 2.5 m.
Use the following parameters in your analysis: M-15kg, m-25kg, k-100 N/m, L-3m and b-2.5m.
