Question

Determine the moment of force about the bolt if you are pulling a wrench of length 0.25 m with a force of 300 N, perpendicular to the wrench

• A. 25 Nm
• B. 50 Nm
• C. 75 Nm
• D. 100 Nm

Answer 1

The correct option is C

75 Nm

As the force is being applied perpendicular to the wrench, perpendicular distance of force = 0.25 m

We know that torque is given by, Torque = Force $\times$ Perpendicular distance

$\Rightarrow$ T = F $\times$ d = 300 N $\times$ 0.25 m = 75 Nm
