A steel bar AD has a cross sectional area of 250 mm^2 and is loaded by a force P1= 5KN, P2 = 10KN and P3 = 6KN. The lengths of the segments are a= 1.5m, b=0.60m, and c=0.90m. E=200,000 MPa. a.) Calculate the change in length of the bar. b.) Determine the stress of member BC. c.) By what amount should the load P3 be increased so that the bar does not change in length when the three loads are applied.
