I the shear stress in steel exceeds about 400 times108nm2


1. If the elastic limit of steel is 5.0 × 108Pa, determine the minimum diameter a steel wire can have if it is to support a 70-kg circus performer without its elastic limit being exceeded.

2. If the shear stress in steel exceeds about 4.00 ×108N/m2, the steel ruptures. Determine the shearing force necessary to (a) shear a steel bolt 1.00 cm in diameter and (b) punch a 1.00-cm-diameter hole in a steel plate 0.500 cm thick.
