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 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
μs = 0.4
