Question

In a bolted joint two members are connected with an axial tightening force of 2200 n. If the bolt used has metric threads of 4 mm pitch, then torque required for achieving the tightening force is

Answer 1

The torque required for achieving the tightening force is 1.4 N-m

Explanation:

Length of threads = 4 mm = 0.004 m

Torque "τ" = F x P / 2 π

Torque "τ" = 2200 x 0.004 / 2 x 3.14

Torque "τ" = 8.8 / 6.28

Torque "τ" = 1.4 N-m

Hence the torque required for achieving the tightening force is 1.4 N-m
