Solve Prob. 8.126 assuming that Î¸ =75°. Problem 8.126: The strap wrench shown is used to grip the pipe firmly without marring the surface of the pipe. Knowing that the coefficient of static friction is the same for all surfaces of contact, determine the smallest value of Î¼s for which the wrench will be self-locking when a = 200 mm, r = 30 mm, and Î¸ =65°.
