## CMVP-400

The CMVP400 is composed of a cantilever beam that oscillates back and forth synchronously with a rotating disc, and the cantilever beam is designed to repeat one cycle at the same amplitude as the disc at the time of one revolution of the disc. If you look at the trajectory of a point on the circumference of the disc moving with time after the disc is set up vertically (with the rim on the front), you can see that it moves by sine wave. This experimental device is a training kit to understand the relationship between displacement, speed and acceleration accurately and to learn the ability to use variables according to application.

### Detailed Description

It is a simple device consisting of a cantilever that vibrates in synchronization with the rotation of the disc. Using a tachometer, the number of revolutions is displayed in revolutions per minute (RPM), so you can get accurate angular velocity (w= 2pf).
Displacement, velocity, and acceleration can be obtained simply by multiplying the radius of the disc (r = 75mm) by the angular velocity (w = 2pf).
