Answer:
A solid cylinder pivoted about the z axis through O. The moment arm of vector T1 is R1, and the moment arm of vector T2 is R2.
A one-piece cylinder is shaped as shown in the figure, with a core section protruding from the larger drum. The cylinder is free to rotate about the central axis shown in the drawing. A rope wrapped around the drum, which has radius R1, exerts a force vector T1 to the right on the cylinder. A rope wrapped around the core, which has radius R2, exerts a force vector T2 downward on the cylinder.
(B) Suppose T1 = 6.5 N, R1 = 1.95 m, T2 = 5.5 N, and R2 =0.75 m. What is the net torque about the rotation axis, and which way does the cylinder rotate starting from rest? -8.55 N*m clockwise
****What if the forces vector T1 and vector T2 both reverse direction, and with new magnitudes vector T1 = 7.7 N and vector T2 = 7.8N. What is the magnitude of the net torque now? (Use the same sign convention for positive and negative torques. The radii R1 and R
