A smooth can C, having a mass of 5 kg, is lifted from a feed at A to a ramp at B by a rotating rod. The rod maintains a constant angular velocity of θ˙ = 0.5 rad/s, Neglect the effects of friction in the calculation and the size of the can so that r=(1.2cos⁡θ)m. The ramp from A to B is circular, having a radius of 600 mm.  (a)  Determine the magnitude of the force which the rod exerts on the can at the instant θθ = 30∘∘. Express your answer to three significant figures and include the appropriate units.

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.
