Finding angular velocity of a rotating bar using energy methods about pin - Method 1
The bar is purely rotating about the pin support, so if we view the bar as rotating around the pin, then the translational component of the kinetic energy will be 0 (because the pin is not moving). The change in gravitational potential...
