A rigid, massless rod has three particles with equal masses attached to it as shown in Figure P8.59. The rod is free to rotate in a vertical plane about a friction-less axle perpendicular to the rod through the point Pand is released from rest in the horizontal position at t - 0. Assuming m and d are known, find (a) the moment of inertia of the system (rod plus particles) about the pivot, (b) the torque acting on the system...

You hold 1.80 N softball in your hand as shown in the figure. Consider your forearm and hand to be a uniform rod with a mass of 1.25 kg and the distance between the elbow on t and the ball in your hand is 2L # 24.0 cm. Your biceps exerts an upward force of 14.0 N on the forearm and is attached at a distance of d :* 2.20 cm from the elbow. Baceps Mg...
The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top.
The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when it starts to rotate clockwise.

4. In the figure shown, rod AB (M-2 kg, L-2 m, center of mass C located 1 m above ground) is kept on a rough surface (H-0.5). A horizontal force F = 10 N is applied to the rod at point D, and distance CD-L/3 m. This horizontal force F causes the rod to rotate about B. Find initial linear acceleration of the top-most point A of the rod. Figure inset shows moment of inertia of a rod. Ignore air...

Two plates, one black (perfectly absorbing) and one mirrored (perfectly reflecting), are affixed one at each end of a 9 cm rod, which is then suspended at its center from a torsion balance (see figure below). The plates are squares whose sides are of length 0.5 cm. A point light source is then placed at a distance 5 m away from the rod, as shown below. The point light source radiates an average power of 41 kW....
