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

A block of mass M = 539.0 g sits on a horizontal tabletop. The
coefficients of static and kinetic friction are 0.549 and 0.391,
respectively, at the contact surface between table and block. The

with the horizontal. a) What angle with respect to the horizontal will
lead to the maximum acceleration in horizontal direction of the block
for a given pushing force? (Give your answer in degrees and use the
unit "deg") b) What is the value of this maximum horizontal
acceleration?

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
