Figure 1.123 shows a vibratory compactor. It consists of a plate cam with three profiled lobes and an oscillating roller follower. As the cam rotates, the roller drops after each rise. Correspondingly, the weight attached at the end of the follower also rises and drops. The

contact between the roller and the cam is maintained by the spring. Design a vibration compactor that can apply a force of \(900 \mathrm{~N}\) at a frequency of \(50 \mathrm{~Hz}\).
