The rigid bar AB of negligible weight is supported by a pin at 0. When the two steel rods are attached to the ends of the bar, there is a gap D= 4 mm between the lower end of the left rod and its pin support at C. Compute the stress in the left rod after its lower end is attached to the support. The cross-sectional areas are 300 mm2 for rod AC and 250 mm2 for rod BD. Use E= 200 GPa for steel. lo/0 0.75 m 1.5m 2 m ANSWER: MPa
