2.4 A rope is wrapped several times around thė hõisting drum of a ship's winch, which rotates continuously. Lift- ing is performed by a man pulling on the free end of the rope. If the load to be lifted is 2 tonnes and a force of 150 N can be applied to the free end of the rope, calculate the number of turns required on the drum. Take u = 0,28. [2,8 turns]

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.
