Question: The two blocks under the double wedge are brought together using a left and right square-threaded screw. If the mean diameter is d, the lead

The two blocks under the double wedge are brought together using a left and right square-threaded screw. If the mean diameter is d, the lead is rl, and the coefficient of static friction is μs , determine the torque needed to spread the blocks apart. The coefficient of static friction between each block and its surfaces of contact is μs.

Units Used:

kN = 103 N

Given:

F = 5 kN

θ = 20 deg

d = 20 mm

rl = 5 mm

μs = 0.4

The two blocks under the double friction between each block an
