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.

Question

Answer the following problem. Show your complete solution. Use 4 decimal places.

1. A hollow steel cylinder surrounds a solid copper cylinder and the assembly is subjected to an axial loading of
200 kN. The cross-sectional area of the steel is 20 c, while that of the copper is 60 cm2 . Both cylinders are
the same length before the load is applied. Determine the temperature rise of the entire system required to
place all of the load on the copper cylinder. The cover plate at the top of the assembly is rigid. For copper E =
100 GPa, a = 17 x 10-6/°C, while for steel E = 200 GPa, a = 12 × 10-6/°C.
