b. Shearing stress in the threads of bolt Given: Diameter of bolt = 7/8 inch Diameter at the root of the thread (bolt) = 0.731 inch Inside diameter of washer = 9/8 inch Vin Tensile stress in the nut = 18 ksi Bearing stress = 800 psi c. Outside diameter of the washer Given: Diameter of bolt = 7/8 inch Diameter at the root of the thread (bolt)= 0.731 inch Inside diameter of washer = 9/8 inch Tensile stress in the nut = 18 ksi Bearing stress = 800 psi O 9/8 in 0.731 + 7/8 5/8 in
