assume 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 0.95 cm in diameter. your response differs from the correct answer by more than 10%. double check your calculations. n (b) determine the shearing force necessary to punch a 1.60-cm-diameter hole in a steel plate 0.450 cm thick.
