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 0.9 kg ball was thrown horizontally with a speed of 3.7 m/s. The ball hits the bottom of the
rigid slender 2.3 kg bar which pivots about its top. Answer the following questions
3.7 m/s
1.8 m
(a) Explain what is happening from time zero to t, i.e., at the instant the ball hits the bar, and
determine the speed of the ball and the angular speed of the bar. It should be a detailed
but concise description of the simple mechanics event.
(b) The effects of restitution on materials colliding are an important subject of study. Based
on your knowledge, why the effects of restitution can be useful in engineering
applications? Predict what would happen to the angular speed of the bar and the linear
speed of the ball just after impact if the coefficient of restitution is 0.7. How would you
interpret the outcome?

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A 0.5-kg ball A is released from rest when the cord attached to it is horizontally placed. When ball A reaches its lowest point, it collides with the stationary ball B (0.4 kg). Right after the collision, ball B gained a velocity of vB3 = 4.65 m/s as shown. Then, ball B falls until it hits the wall that is located at a horizontal distance of 1.5 m. Determine the length L of the cord. Also, find the velocity of ball B, vB5, just after it hits the wall. The coefficient of restitution for all the collisions is e = 0.8.
