Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

The corediameter of the double start square threaded screw having a pitch of 12mm is 50 mm. A load of 18kN is lifted through a distance of 180mm. Find the work done(in Joule)in lifting the loadand the efficiency of the screw, when 1. The load rotates with the screw, and 2. The load rests on the loose head which does not rotate with the screw. The external and internal diameter of the bearing surface of the loose head are 60 mm and 10 mmrespectively. The coefficient of friction for the screw is 0.11,whilefor the bearing surface is 0.13.
