A rigid block AB of weight 800 N hangs on an equally spaced vertical wires, two of steel and one aluminum. The wires also support a load P acting at the midpoint of the block. The diameter of the steel wire is 2 mm and that of aluminum wire is 4 mm. what load P can be supported if the allowable stress in the steel wires is 220 MPa and in the aluminum wire is 80 MPa. Use E = 200 GPa for steel and 70 GPa for aluminum. St Al St A W = 800 N P

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
