A $30.0 \mathrm{~cm}$ wrench is used to generate a torque at a bolt. A force of $40 \mathrm{~N}$ is applied perpendicularly at the end of the wrench. The torque generated at the bolt is
A) $9.0 \mathrm{~N} \cdot \mathrm{m}$.
B) $7.0 \mathrm{~N} \cdot \mathrm{m}$.
C) $12 \mathrm{~N} \cdot \mathrm{m}$.
D) $20 \mathrm{~N} \cdot \mathrm{m}$.
E) $5.0 \mathrm{~N} \cdot \mathrm{m}$.

Question

Quizplus · Accepted Answer

Torque is calculated as the product of force and the perpendicular distance from the pivot point, which in this case is $Torque = 40 \mathrm{~N} \times 0.30 \mathrm{~m} = 12 \mathrm{~N} \cdot \mathrm{m}$.
