![In the figure below the clamping force on the pipe is (331.7 lb), knowing that a single threaded screw Acme
with major diameter (1 in) is used with coefficient of sliding friction (0.2135) and booth screw and nut are made
from 1030- hot rolled Carbon Steel. If the collar has a rolling friction of 0.02 and the mean collar diameter is
1.75 in.
Determine:
1- The tightening and loosening torques. Is it self-locking?
2- Thread screw and nut induced stresses.
