Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

One end of the cableDesign A: Design B: will be attached to the material while the other end will be permanently fixed to a drum (cylinder) so that as the drum is rotated the cable is wound around its outside surface. Two designs for a drum are being considered for use in the system. Design “A” calls for a solid aluminum pulley ( palluminium = 2800 kg/m 3 ) while design “B” calls for a steel pulley (psteel= 8000 kg/m 3 ) that is hollow (it can be modeled as a 12 mm thick shell).
