# Torque on a Bar with Mass

APPH12-RQ2JQ5

Shown in the image is a freely rotating bar with mass currently at rest with the axis of rotation marked by an $X$. The bar's mass of $5\text{ kg}$ is uniformly distributed the bar has a length, $L$, of $2\text{ m}$. Two forces are applied to the ends of the bar as shown in the image.

What is the net torque on the bar due to all external forces?

A

$26.64\ \mathrm{N\cdot m}$

B

$36.04\ \mathrm{N\cdot m}$

C

$4.62\ \mathrm{N\cdot m}$

D

$2.12\ \mathrm{N\cdot m}$
