Lecture-04_degrees-of-freedom

This video covers some concepts about how to describe a system with moving parts:

  1. degrees of freedom

  2. generalized coordinates

These two concepts are very important in Lagrangian dynamics.

  • What are other constraints in dynamic systems (others than hinges and prismatic joints)?

  • How would you describe the constraints on the Ex. 1 pendulum? Why is there only one degree of freedom?
