Linear Flexible Joint
Teach the fundamentals of dynamics and control
The Linear Flexible Joint is a passive linear cart that connects to the Linear Servo Base Unit through a linear spring. As an implementation of the classical mass-damper-spring quadratic system, the linear flexible joint is an ideal textbook-type experiment. The experiment is useful in the study of vibration analysis and resonance.
