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.

The mechanism shown is a special platform used to raise sections of a structure for the construction of a tower. Assembly A has a mass of 3000 kg and is lifted by platform B which has a mass of 2000 kg. The platform moves upwards guided by the vertical column by means of rollers, as the movement is activated by the hydraulic piston CD and the parts EDF and FH. For the position shown, determine the magnitude of the minimum force that must be exerted by the hydraulic piston to start the lifting motion. (Considerable value will be placed on the correct completion of free-body diagrams. Use as much space as you feel necessary to keep the D.C.L.s clear and complete.)
