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.

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me? The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy. Assume that the weight of the child is equally distributed across all of the points indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required to determine the following: 1) Draw a free-body diagram of the structure 2) Simplify the Free…
4-64. Analytically calculate the maximumn linear dis- placement (stroke) of the blade for the shearing mechanism shown in Figure P4.7.
Consider the system shown in FIGURE P3-44 of the textbook. The designer has made several changes to the system. These changes are: • the load of 6 kN/m has been changed to 11 kN/m, • the central length of 2 m has been changed to 4 m o this means the load is applied over the beam from 1 m to the right of point 'A' TO point 'C'. What is the magnitude of the resultant of the distributed load? O 5 kN O 55 kN O 0.513 kN O 93.6 kN O 11 kN O 12.1 kN O 91.4 kN O O kN

You are sitting in a chair and you are ready to kick a soccer ball from a sitting position using only your quadriceps muscles to rotate your knee. Be sure you will not pivot your hips, as you are sitting in the chair; we want to simplify this problem to include only rotating your lower leg at the knee joint and keeping your thigh firmly fixed to the seat. For our purposes, your quadriceps muscles can be treated as a single string that exerts a tension on the knee at a right angle from a lever arm of 2.00 cm. The knee is connected to a plausible 50.0 cm lower leg as measured from the pivot point of the knee to the contact point where we will kick the ball.Before we kick it, we would like to balance the ball on our contact point (at our ankle, say) 50.0 cm away from the pivot point of the knee by extending the lower leg straight out (upper leg aligned with the lower leg). The soccer ball has a mass of 400 grams. We will neglect all mass of all parts of the leg here for brevity c) We now…
