a = = The uniform 20 kg slender bar AC rotates in a vertical plane about the pin at B. The spring AD has a spring constant k 15 N/m and an undeformed (unstretched) length Lo = 2 m. The bar is initially at rest in the position 0° (vertical). It is then released from this position. Due to gravity, the bar AC starts to rotate clockwise. Find the angular velocity of the bar when 0 = 90° (horizontal) using principle of work and energy. 120-kg- 4 m 3 m B 2 m
