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.

### Problem 14.57

The 23 lb collar starts from rest at point \( A \) and is lifted with a constant speed of 10 ft/s along the smooth rod.

#### Figure 1
The accompanying diagram illustrates the setup for the problem:

1. A vertical rod is depicted, with a collar initially positioned at point \( A \).
2. The collar is 4 feet from the base and travels upward along the rod.
3. The movement of the collar is facilitated by a pulley system.
4. The pulley is mounted on a horizontal support beam 3 feet to the right of the rod's top.
5. A force \( F \) is shown acting downward from the pulley towards the collar, creating an angle \( \theta \) with the vertical rod.
6. The figure provides a visual representation of these measurements and forces acting on the system.

The problem involves analyzing the forces and the motion of the collar as it ascends the rod. The constant speed of 10 ft/s indicates that the primary force calculations would involve equilibrium conditions where acceleration is zero.

Learning Goal: In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: • First law: A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force. Second law: A particle acted upon by an unbalanced force, F experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force.
