Question:

None 0.2: The rigid platform has negligible mass and rests on two steel bars, each 250.00 mmlong. The center bar is aluminum and 249.90 mm long. Compute the stress in the aluminumbar after the center load P 400 kN has been applied. For each steel bar, the area is 1200mm2 and E= 200 GPa. For the aluminum bar, the area is 2400 mm2 and E= 70 GPa.
