Q3:- The Fig. below shows an epicyclic gear train in which the gear D is held stationary by shaft A and arm B is rotating at 200 rpm ccw. The gears E and F are carried by the arm. The gear G is rigidly attached to shaft C. Find the magnitude and direction of the speed of shaft C. If the gear train is transmitted 7.5 kW what is the torque required to hold shaft A stationary? Given that Z;-40, Z=30 and Ze=20. B C D

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.
