The system is released from rest with θ = 90°. Determine and plot dθ/dt as a function of θ. Determine the maximum magnitude of dθ/dt in the ensuing motion and the value of θ at which it occurs. Also find the minimum value of θ. Use the values m1 = 2.15 kg, m2 = 1.63 kg, and b = 0.82 m. Neglect friction and the mass of bar OB, and treat the body B as a particle.
