The automobile jack is subjected to a vertical load of F = 8 kN. If a square-threaded

Question:

The automobile jack is subjected to a vertical load of F = 8 kN. If a square-threaded screw, having a lead of 5 mm and a mean diameter of 10 mm, is used in the jack, determine the force that must be applied perpendicular to the handle to

(a) Raise the load, and

(b) Lower the load; μ_s = 0.2. The supporting plate exerts only vertical forces at A and B.
