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.

At the instant given, shown in the figure below, the angular velocity and angular acceleration of bar B1 are 0.28 O rad/sec and 0.12 O rad/sec?. Find the magnitude of angular acceleration of B3 at this instant. B, 18 15 B, 24" 30" Hint: You can use the two point formula for velocity to go from one support to the other. The velocity at the first support is zero, the velocity calculated at the other end is dependent on the two unknown angular speeds. Use the fact the velocity at the other support is zero to calculate the two angular velocities. Similarly, use the two point formula for acceleration to go from one support to the other. Again the acceleration of the supports is zero which can be used to calculate the two angular accelerations. Figure is from "Engineering Mechanic An Introduction to Dynamics", McGill and King.
