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.
