Question 45

Easy

Figure 1 shows a uniform wooden bar with a pivot at one end.

A downward force, $F$ , acts on the bar.

A horizontal wooden bar with a pivot at its left end. A vertical downward force arrow labelled F = 15 N is shown acting on the bar at a distance of 40 cm from the pivot.

Calculate the moment of the force, $F$ , about the pivot.

Give your answer in Nm. Use the equation:

\text{moment of a force} = \text{force} \times \text{distance from pivot}
