IV.An Aluminum bar AD (see figure) has a cross-sectional area of 250 mm2 and isloaded by forces P1 = 7560 N, P2 = 5340 N, and P3 = 5780 N. The lengths of thesegments of the bar are a = 1525 mm, b = 610 mm, and c = 910 mm.(a) Assuming that the modulus of elasticity is E = 72 GPa, calculate the change inlength of the bar. Does the bar elongate or shorten?(b) By what amount P should the load P3 be increased so that the bar does notchange in length when the three loads are applied?(c) If P3 remains at 5780 N, what revised cross-sectional area for segment AB willresult in no change of length when all three loads are applied?AkaB₁P₁bCP₂-P3
