250 kg concrete wheel with a radius of 1.50 m is being pulled up a hill by a 725 kg cow, with a rope attached to the wheel and the cow. There is a 35.5 cm tall rock protruding out of the hill.  Calculate the tension in the rope when the barrel is just starting to lift off of the hill to go over the protruding rock? What's the minimum coefficient of static friction between the cow and the hill for the cow to be able to pull the barrel over the rock?

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.
