## What is the equation of a cycloid?

cycloid, the curve generated by a point on the circumference of a circle that rolls along a straight line. If r is the radius of the circle and θ (theta) is the angular displacement of the circle, then the polar equations of the curve are x = r(θ – sin θ) and y = r(1 – cos θ).

**Which of the following displacement diagram should be chosen for better dynamic performance of a cam follower mechanism?**

11. Which of the following displacement diagrams should be chosen for better dynamic performance of a cam-follower mechanism? Explanation: Only cycloidal motion gives maximum acceletation. Hence, it is considered the most dynamic cam- follower mechanism.

### How are the displacement and velocity diagrams used in cam design?

The displacement, velocity and acceleration diagrams are plotted for one cycle of operation i.e., one rotation of the cam. Displacement diagrams are basic requirements for the construction of cam profiles.

**How to plot the follower displacement of the cam?**

The displacement of the follower is plotted along the y-axis and angular displacement θ of the cam is plotted along x-axis. From the displacement diagram, velocity and acceleration of the follower can also be plotted for different angular displacements θ of the cam.

#### How do I design a CAM system?

•Design a cam system to: 1. Open a valve 0.05 inches in 0.0025 seconds 2. Stay open for 0.0050 seconds 3. Close in 0.0025 seconds, and 4. Stay closed for 0.02 seconds. 5. Repeat continuously. 2 0.05 y(in) t(s) 0 0 0.001
