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.

Question

The flywheel (I = mk² ) shown has a radius of 20 in. a weight of 250 lbs, and a radius of
gyration of 15 in. A 30-lb block A is attached to a wire that is wrapped around the

A disk with radius R and mass m begins from rest and then moves without slipping while being pulled horizontall by a force P acting at its center axle. Show that the velocity of the wheel after T seconds is v= 2PT/3m. (Hint: use both linear and angular-impulse principles.) m REG P ¹The radius of gyration has units of length and is related to the inertia by k = IG/m. It corresponds to the distance at which a mass equivalent to the mass of the rigid body would produce the same inertia as the actual rigid body. Recall that the inertia of a particle of mass m at a distance r from an axis of ortation is mr². Rather that using r the convention is to define the radus of gyration with the symbol k.

An object of mass m1 slides on a sloped block of mass M2, which in turn slides on a horizontal surface. The slope angle is a constant 3, and both masses are initially at rest. There is no friction between any of the objects, and the masses are subject to the force of gravity -mgêy. Use as co- ordinates the horizontal position x2 of mass m2, and the height y1 of mass m1, as shown in the y4 Y1 M2 x2 diagram to the right. Find the equation of motion of block 2, ä2(t). The expression should only include expressions involving constants: M2, m1, g, and B.
