Question: The square-threaded bolt is used to join two plates together. If the bolt has a mean diameter of d = 20 mm and a lead

The square-threaded bolt is used to join two plates together. If the bolt has a mean diameter of d = 20 mm and a lead of l = 3 mm. determine the smallest torque M required to loosen the bolt if the tension in the bolt is T = 40 kN. The coefficient of static friction between the threads and the bolt is μ_s = 0.15. d . > M

d . > M
