Problem

A uniform meterstick is pivoted at its 50\,cm mark and is held horizontal. Three forces act on the stick as listed below. • 5\,N downward at the 20\,cm mark • 5\,N upward at the 80\,cm mark • 10\,N downward at the 50\,cm mark Which force produces zero torque about the pivot? (a) The

5\,\text N

upward force at the

80\,\text{cm}

mark (b) The

10\,\text N

downward force at the

50\,\text{cm}

mark (c) The

5\,\text N

downward force at the

20\,\text{cm}

mark (d) All three forces produce non-zero torque
