The 14.6 lb lever OA with 9.6 in radius of gyration about O is initially at rest in the vertical position (?= 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 ? = 5.9 rad/sec as the lever reaches the horizontal position ? = 0.

The 14.6 lb lever OA with 9.6 in radius of gyration about O is initially at rest in the vertical position (?= 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 ? = 5.9 rad/sec as the lever reaches the horizontal position ? = 0.

The 14.6-lb lever OA with 9.6-in. radius of gyration about O is initially at rest in the vertical position (0 = 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.
