he shaft has a square-threaded screw with a lead of 8 mm
Chapter 8, Problem 8-75(choose chapter or problem)
The shaft has a square-threaded screw with a lead of 8 mm and a mean radius of 15 mm. If it is in contact with a plate gear having a mean radius of 30 mm, determine the resisting torque M on the plate gear which can be overcome if a torque of \(7\ N \cdot m\) is applied to the shaft. The coefficient of static friction at the screw is \(\mu_B = 0.2\). Neglect friction of the bearings located at A and B.
