Question

The connection shown is subjected to an external load of 1124 lbf. The bolt is SAE 8 grade steel with UNF thread. (a) Determine the bolt diameter using the equation for unknown initial tension. (b) Calculate the initial tension and the corresponding torque if Si = 0.75Sp. The bolts must be lubricated before tightening. (c) Calculate the factor of safety based on the ultimate strength and the factor of safety with respect to the part spacing.

Step 1

The equation for unknown initial tension in a bolted joint is: T = K * F where: T = initial tension in the bolt K = bolt stiffness (dependent on material and geometry) F = external load applied to the joint Given: F = 1124 lbf Show more…
