Question

A 150 lb diver stands at the end of a rigid 8 ft long diving board. What is the magnitude of the torque the diver exerts on the diving board

Answer 1

1200 lb-ft

Step-by-step explanation:

Weight of diver W = 150 lb

length of board L = 8 ft

This board is pivoted at one end therefore, the perpendicular distance from the pivot = 8 ft

Torque = weight x perpendicular distance from pivot

T = WL

Torque = 150 x 8 = 1200 lb-ft
