etermine the elongation of a 0.5-in, dianeter sterl bar The elastic modulus of the steel bar is 27000 kar. 2000 Ib 10 ft

02: The rigid platform has negligible mass and rests on two steel bars, each 250.00 mm long. The center bar is aluminum and 249.90 mm long. Compute the stress in the aluminum bar after the center load P= 400 kN has been applied. For each steel bar, the area is 1200 mm2 and E= 200 GPa. For the aluminum bar, the area is 2400 mm2 and E 70 GPa Rigid platform Steel Ahmum Steel
