A crate of mass 80 kg, 1.2 m long and 0.5 m high, rests with its bottom edge CD horizontal. Point E lies on CD, 0.35 m from C and 0.85 m from D; A is the top-left corner (directly above C). The weight acts at the centre of the crate. Determine (a) the moment of the weight about E; (b) the smallest force applied at A that creates a moment of equal magnitude and opposite sense about E; (c) the smallest vertical force applied on the bottom edge CD that does the same. (answers in N·m, N and N)
