Two solid spherical masses mı = 2.51 kg and m3 = 1.48 kg with radii r1 = 0.21 and r2 = 0.14, are attached to the end of a massive rigid rod of mass m2 = 1.00 kg, as shown in the below figure. The rod is attached to a massive cylinder of mass m4 = 3.2 kg and radius r4 = 0.14 m, and is free to rotate in a vertical plane about a frictionless axle perpendicular to the rod through point P a distance l1 = 0.83 m and l = 0.52 m. The bar is released from rest in the horizontal position at t = 0.
