Lecture_01 - pendulum in a rotating frame¶
In this lecture, you look at the virtual displacements and virtual work in a rotating reference frame.
For a system, with frame arms, \(a=1~m\) and pendulum arm \(l=1~m\), at what rotation rate will the system not oscillate? e.g. when natural frequency is \(0~rad/s\)?
In a Newtonian system of equations, you would consider the reaction forces of every body. Why do we ignore virtual work for spinning, hinges, and other reactions?
