Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

A shaft with 3 meters span between two bearings carries three masses of 10 kg, 20 kg and 15 acting at the extremities of the arms 45 mm, 60 mm and 50 mm long respectively. The planes in which these masses rotate are 1.2 m, 2.4 m and 3 m respectively from the left end bearing supporting the shaft. The angle between the arms is 60°. The speed of rotation of the shaft ist 50 r.p.m. If the masses are balanced by two counter-masses rotating with the shaft acting at radii of 0.03 m and placed at 0.2 m from each bearing centers, estimate the magnitude of the two balance masses and their orientation with respect to the X-axis, i.e., mass,of 10 kg.
