Question

Additional instructions: Treat the m masses as point particles. The rod is uniform and has mass 3m. Also calculate the rods instantaneous angular acceleration upon release from its initial horizontal orientation.

two blocks, each of mass m, are attached to the end of a massless rod which pivots. Iinitially the rod is held in the horizontal position and then released. calculate the magnitude and direction of the net torque on this system when it is first released. Additional instructions: Treat the m masses as point particles. The rod is uniform and has mass 3m. Also calculate the rod½s instantaneous angular acceleration upon release from its initial horizontal orientation.

Explanation / Answer

mg ( L2 - L1) clockwise, N-m
