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.

An open belt 100 mm wide connects two pulleys mounted on parallel shafts with their centres 2.4 m
apart. The diameter of the larger pulley is 450 mm and that of the smaller pulley 300 mm. The coeffi-
cient of friction between the belt and the pulley is 0.3 and the maximum stress in the belt is limited to
14 N/mm width. If the larger pulley rotates at 120 r.p.m., find the maximum power that can be trans-
mitted.
