Question

Robin is standing terrified at the end of a diving board, which is high above the water. If Robin has a mass of 76 kg and is standing 1.6 m from the board's pivot point, what torque is Robin exerting on the board

Answer 1

Torque = 1191.68 N-m

Step-by-step explanation:

Given data

mass m = 76 kg

standingdistance r = 1.6 m

Solution

we get here torque that si express as

torque = force × distance ................1

torque = r × F sin(theta)

and we know that

F = mg .........2

and g = 9.8 m/s²

put here value in equation 1 we get

Torque = 76 × 1.6 × 9.8 × sin(90)

Torque = 1191.68 N-m
