To apply the work-energy theorem.An alpine rescue team member must propel a box of supplies, with mass m, up an incline that makes an angle θ with the horizontal so that it reaches a stranded skier who is a vertical distance h above the bottom of the incline. The incline is slippery, but there is some friction present; the kinetic friction coefficient is μk.   Use the work-energy theorem to calculate the minimum speed, v, that the member must impart to the box at the bottom of the incline so that it will reach the skier. Express your answer in terms of some or all of the variables m, g, h, μk, and θ.

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.
