Calculating Net Torque on a Disk
A disk of radius R is subjected to three forces, each of magnitude 5 N, applied at its edge. The forces are directed at angles of 0°, 120°, and 240° with respect to a horizontal axis. What is the magnitude of the net torque on the disk about its center?
A
15R N·m
B
0 N·m
C
5R N·m
D
7.5R N·m
