Problem 1a.3 The rigid bar ABD is supported by a journal bearing (radial bearing) at A, a vertical rope at B, and by a ball-and-socket joint at D. The bar is acted on by a weight attached to a fixed collar at E. Draw a complete Free Body Diagram of the bar (neglect the weight of the bar). Radial bearings do not resist forces along the line of the shaft (i.e. it resists only forces that are radial to the shaft.) a) State the number of unknown supports acting on the bar. b) State whether the bar is STATICALLY DETERMINATE or NOT STATICALLY DETERMINATE. Also state whether it is STABLE or UNSTABLE. 0.5 m C A 1 m B E 0.5 m N D x 100 kg y
