Question

Three bars, two made of aluminum and one made of steel, support a rigid block. An object of weight W is dropped vertically from a distance h above the rigid block. Both steel and aluminum bars have cross-sectional area of 50 mm2 and length of 0.5 m. The elastic moduli for the aluminum and steel are 76 GPa and 184 GPa, respectively.

a) If W=1000N and h=0.1m, determine whether the three bars are still safe to perform.

b) If h=0.2m, determine the maximum weight that can be dropped without causing failure to the bars
