Two identical 16-kg spheres are attached to the light rigid rod, which rotates in the horizontal plane centered at pin Part A: If the spheres are subjected to tangential forces of P = 10 N, and the rod is subjected to a couple moment M=(8t)N⋅mM=(8t)N⋅m, where t is in seconds, determine the speed of the spheres at the instant t = 4 s. The system starts from rest. Neglect the size of the spheres.
Express your answer to three significant figures and include the appropriate units.
The ball with a mass of 5 kg is attached to the rod (with negligible mass), which rotates about O in the horizontal plane. A couple moment M = 0.5 t2 N-m is applied to the system, where t is in seconds. Determine the speed of the ball at the instant t = 10 s starting from rest.
