Problem: The solid dot shown in Fig. 8–36 is a pivot point. The board can rotate about the pivot. Which force shown exerts the largest magnitude torque on the board?

FREE Expert Solution

Torque is expressed as:

τ=r×F=rFsinθ, where r is the distance between the force and the pivot, F is the magnitude of the force, and θ is the angle between r and F.

(a)

F = 1000 N

r = 0 m

τ1000N = (0)(1000)sinθ = 0 m•N
