APFIVE Calculating Net Torque on a Disk
A disk of radius R has three forces applied at its edge: F₁ = 5 N at 0° from the horizontal, F₂ = 5 N at 120° from the horizontal, and F₃ = 5 N at 240° from the horizontal. What is the magnitude of the net torque about the center of the disk?
A
0 N·m
B
7.5R N·m
C
15R N·m
D
5R N·m
