Question: In the vise shown, the screw is single-threaded in the upper member; it passes through the lower member and is held by a frictionless washer.

In the vise shown, the screw is single-threaded in the upper member; it passes through the lower member and is held by a frictionless washer. The pitch of the screw is 3 mm, its mean radius is 12 mm, and the coefficient of static friction is 0.15. Determine the magnitude P of the forces exerted by the jaws when a 60-N∙m couple is applied to the screw. D C 450 mm A B 60 N-m 150 mm P -P

D C 450 mm A B 60 N-m 150 mm P -P
