- The position of the small 0.68-kg blocks in the smooth radial slots in the disk which rotates about a vertical axis at O is used to activate a speed-control mechanism. If each block moves from r = 162 mm to r = 200 mm while the speed of the disk changes slowly from 272 rev/min to 382 rev/min, design the spring by calculating the spring constant k of each spring. The springs are attached to the inner ends of the slots and to the blocks.arrow_forwardQ8: The 25-kg bar BD is attached to the two light links AB and CD and moves in the vertical plane.

- C14-2. As the large ring rotates, the operator can apply a breaking mechanism that binds the cars to the ring, which then allows the cars to rotate with the ring. Assuming the passengers are not belted into the cars, determine the smallest speed of the ring (cars) so that no passenger will fall out. When should the operator release the brake so that the cars can achieve their greatest speed as they slide freely on the ring? Estimate the greatest normal force of the seat on a passenger when this speed is reached. Use numerical values to explain your answer.arrow_forwardThe 1.8-kg slider fits loosely in the smooth slot of the disk, which rotates about a vertical axis through point O.
