Given: (PK 4thEd 14.138) The 8 foot long cylindrical shaped rod OA, has a surface roughness of = 0.5, is rotating freely about the vertical-axis with an angular speed -30d in the direction shown. The collar B has weight WB = 8 lbf and is attached to the spring as shown. The spring has a stiffness of k-4.5 and an uncompressed length of Lo = 4 ft as is attached to the end of the rod at A. There is a cord restraining the collar B. At this moment the system is jolted with an angular acceleration of 0 = 50. 1.5 ft 6.5 ft 0 k Find: Determine the 1. Force in the spring, 2. Total Normal force acting on the collar, & 3. Tension in the cord attached to the collar. Wa
