Diagram (b) is a free-body force diagram for the cupboard. *State the magnitude of force Y.

*Explain why forces X and P must have equal magnitude.

*Calculate the moment of the weight of the cupboard about a point A.
Moment=?

*Calculate the value of force X when h=0.60 m.
Force X=?

*In principle the fixing screws could be positioned anywhere between point A and the top of the
cupboard. Sketch a graph to show how the size of force X would depend on h for values of h from
zero up to 0.60 m.

(*) Mark is qustions.
