Question:

The diagram below shows apparatus for investigating moments of forces.

The uniform metre rule shown in the diagram above is in equilibrium.

a. Write down two conditions for the metre rule to be in equilibrium.

b. Show that the value of the reading on the spring balance is 8.0 N.

c. The weight of the uniform metre rule is 1.5 N. Calculate the force exerted by the pivot on the metre rule and give its direction.
