Given Particles A and B having masses of 2m and m respective
     Given: Particles A and B (having masses of 2m and m, respectively) are attached to a rod with a length of L and with negligible mass. The bar is released from rest at when it is at an angle of theta_1 from the vertical, as shown below for Position 1. At the instant when the bar passes through the vertical position (Position 2), particle A is released from the bar, with particle B remaining attached to the bar.  Find: Find the maximum angle theta_3 reached by the bar after particle A is released.  Use the following parameters in your analysis: theta_1 = 56.13 degree, m = 10 kg and L = 3 m. 
  
  Solution
a) 17.3
