A pesky rabbit has been feeding on Mrs. Cromwell's prized flowers. In order to put an end to this she devised the simple trap below to catch the rabbit. The crate weighs 6.5b and is supported by stick BC. Find the magnitude and direction of the reaction at A and the compression force in stick BC using (a) the concepts of two and three-force bodies (closed polygon method discussed in chapter 2). (b) Check your answers by doing sum of the forces and moments. Answer(s): 6.5 60° A. 8h 40 A pesky rabbit has been feeding on Mrs. Cromwell's prized flowers.
