A uniform solid disk is mounted on an axle in such a way that it is free to rotate about a horizontal axis. The radius of the disk is 0.450 m and its mass is 25.5 kg. As shown in the diagram, two forces F1 = 91.0 N and F2 = 115 N applied to the disk sets the disk rotating with a constant angular acceleration.... show more A uniform solid disk is mounted on an axle in such a way that it is free to rotate about a horizontal axis. The radius of the disk is 0.450 m and its mass is 25.5 kg. As shown in the diagram, two forces
F1 = 91.0 N
and
F2 = 115 N
applied to the disk sets the disk rotating with a constant angular acceleration. Assume the axle is frictionless.
A solid disk on an axle has two arrows tangent to its surface, one on the top and one on the bottom, both pointing to the right. The top tangent arrow pointing to the right is labeled vector F_2. The bottom tangent arrow pointing to the right is labeled vector F_1. The vector F_2 is larger than the vector F_1.
(a)
Calculate the magnitude and direction of the net torque produced by the two forces.

(b)
Determine the magnitude of the angular acceleration of the disk.
