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[l b], 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 l0=1.2[ft]. The spring remains in horizontal position throughout the motion due to the roller guide at B. Determine angular velocity of...
