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.

7. A ladder of length 12 m leaning up against a wall makes a 50 degree angle with the ground. The top of the ladder has sliders so that it can slide up and down the wall. Therefore, consider the top of the ladder to be frictionless. The ladder has a weight of 189 N that acts at its center. Someone weighing Fg = 1000 N is 0.92 m vertically below B, but on the ladder.
