QUESTION:
Determine the clamping force on the board A if the screw is tightened with a torque of M = 8 N \(\cdot\) m. The square-threaded screw has a mean radius of 10 mm and a lead of 3 mm, and the coefficient of static friction is \(\mu_{\mathrm{s}}\) = 0.35.
ANSWER:
Step 1 of 4
Note that the clamping force is equal to the force in the screw
Since we want to tighter the screw, the moment equilibrium equation is
From here we can express as:
…(1)
