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.

A 25.5 kg mass (m) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left (T) ) of the mass makes an angle of 0.00 with the horizontal, and the cable to the right (T;) makes an angle (02) of 40.6. If the mass is at rest, what is the tension in each of the cables, T and T; ? The acceleration due to gravity is g = 9.81 m/s?. T T = 123.52 N 123.52 TOOLS x10
Show complete solutions. Please draw the figure or the illustrations. Problem:Two horses are pulling a barge with mass 2000 kg along a canal, as shown in the Figure. The cable connected to the first horse makes an angle of 30o with respect to the direction of the canal, while the cable connected to the second horse makes an angle of 45.0o. Find the initial acceleration of the barge, starting at rest, if each horse exerts a force of magnitude 600 N on the barge. Ignore forces of resistance on the barge.
Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of 0 = 19.0⁰. Suppose you want the wedge and the rod to start from rest and move with constant acceleration, with the rod moving upward 1.00 mm in 8.00 ms. Take m…
