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.

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight legraising with 10 lb weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and(2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm,distance of the weight is 80 cm, and the COM is 45 cm from the joint. ANSWER THE QUESTION: 1.) Assuming that the leg moves at 0. 9 seconds, compute for the angular velocity. GIVEN: Leg length = 84 cm = 0.84 m Distance of the muscle from the joint = 54 cm = 0.54 m Distance of the weight = 80 cm = 0.80 m Distance of the COM from the joint = 45 cm = 0.45 m Mass = 10 lb = 4.535 kg Linear displacement x = 38.971 cm Or x = 0.389 m
