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.

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. Topic: Conservation of Energy Principle A 0.2-kg block slides along a frictionless curved pipe a shown. It is connected to a spring with a spring constant of k = 32.5 N/m . The uncompressed length of the spring is Lo = 1.5 m. Determine the speed of the spring at point 2 if it starts from rest at point 1.
During braking, a truck has a steady deceleration of 7.0 m/s². A box sits on the platform of this truck. The box begins to slide when the braking begins and, after sliding a distance of 2.0 m (relative to the truck), it hits the front of the truck. With what speed (relative to the truck) does the box hit? The coefficient of kinetic friction for the box is μk=0.50.
The spring is initially compressed 0.5 m, and block A is released from rest, in the position shown in the figure. After traveling 2 m, block A collides with block B (e = 0.9), and block B goes up a smooth circular curve. If WA = 12 N and WB = 2 N. Determine: a) the speed of A just before the collision; b) the speed of each block after the collision; c) the normal force on B, at position (2).
