Problem

A uniform lever of length

0.25\,\text{m}

extends horizontally from a pivot. A force with components

F_x = 12\,\text{N}

and

F_y = 16\,\text{N}

(

+y

is upward) is applied at the free end. What is the magnitude of the torque about the pivot due to this force? a)

3.0\,\text{N}\!\cdot\!\text{m}

5.0\,\text{N}\!\cdot\!\text{m}

4.0\,\text{N}\!\cdot\!\text{m}

2.0\,\text{N}\!\cdot\!\text{m}
