Concept explainers

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

Question

The crane shown in the figure is lifting a 186-kg crate upward with an acceleration of 4.21 m/s². The cable from the crate passes over a
solid cylindrical pulley at the top of the boom. The pulley has a mass of 195 kg. The cable is then wound onto a hollow cylindrical drum
that is mounted on the deck of the crane. The mass of the drum is 136 kg, and its radius (the same as that of the pulley) is 0.198 m. The
engine applies a counterclockwise torque to the drum in order to wind up the cable. What is the magnitude of this torque? Ignore the
mass of the cable.
