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.

Shown in the figure below is a magazine resting on top of a book. There is static friction between the magazine and the book and there is kinetic friction between the book and the table. If you pull very gently on the book, both objects slide together. If you pull very forcefully, you will slide the book out from under the magazine. In this problem, we will determine the MAXIMUM FORCE that you can apply and still have the magazine come along for the ride.

Work-energy principle A 10 lb package moves down a conveyor belt and transition to a ramp. The angle of both the conveyor belt and the ramp = 12 degrees. (The length of the ramp = 10 ft (This is different than in the figure). The coefficient of kinetic (sliding) friction is mu_k = 0.40. Compute the work done by the friction as it slides on the ramp. Compute the height difference from the top to the bottom of the ramp. Compute the gravitational potential energy at the top relative to the bottom. The velocity at the end of the ramp = 2 ft/s. Compute the kinetic energy at the bottom. Use the work-energy principal to compute the kinetic energy at the top of the beginning of the ramp. Then, compute what the velocity at the top must have been.
A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of 0 just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? Finally, if the inclined plane became icy, and the rope didn't break as the cask slipped, what would be remarkable about the lines of action of the W, N and T force vectors once equilibrium was re-established? 0.70 m 40
