Problem: Assume that if the shear stress in steel exceeds about 4.00 108 N/m2, the steel ruptures. (a) Determine the shearing force necessary to shear a steel bolt 1.20 cm in diameter. N (b) Determine the shearing force necessary to punch a 1.75-cm-diameter hole in a steel plate 0.660 cm thick.

FREE Expert Solution

a)

Shearing force = (shear stress)(Area)

Area = πr2 = π (d/2)2 = π(1.2 × 10-2/2)2 = 1.130973355 × 10-4 m2
