The ends of two fixed rods an and b are each made in the form of a single threaded screw of mean radius 6mm and pitch 2mm. rod a has a right handed thread and rod b has a left handed thread. the coefficient of static friction between the rods and the rods and the threaded sleeve is 0.12. determine the magnitude of the couple that must be applied to the sleeve in order to draw the rods closer
