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.

If VA = 96.2 i in/sec in the figure below, find w2, the angular speed of bar B2. By 12 in. Bs B8 in. i -10 in. To calculate the angular speeds of the two bars B2 and B3, you need to use the two point formula: 1) fırst on rigid body B2 to calculate the velocity of point B (since you know velocity at point A) 2) then on rigid body B3 to calculate the velocity of point D (since you know velocity at point B) 3) Note that the velocity at point D has to be zero. Thus the two components of the velocity are zero giving you two equations to solve for the two unknown angular velocities.
