The 14.6-lb lever OA with 9.6-in. radius of gyration about O is initially at rest in the vertical position (8= 90°) where the attached spring of stiffness k = 4.3 lb/in. is unstretched. Calculate the constant moment M applied to the lever through its shaft at O which will give the lever an angular velocity w = 5.9 rad/sec as the lever reaches the horizontal position 0 = 0. k= 4.3 lb/in, 13.6". 7.6" 13.6"
