Determine angular velocity of the bar, [rad/s], when it goes through horizontal position? The bar, WA= 100 [lb] and L=3 [ft], shown in figure is initially in the vertical position. The bar is subjected to a couple moment of M=20 [lb-ft] and a force F=50 [lb], which is always perpendicular to the end of bar. Also, the spring is attached to bar at distance L/2 from point A, and has unstretched length of lo=1.2 [ft]. The spring remains in horizontal position throughout the motion due to the roller guide at B. Determine angular velocity of the bar, o [rad/s], when it goes through horizontal position.
