The question is to write the Laplace transformed equations of motion for the system
Homework Equations
The Attempt at a Solution
I am confused about a couple of things: why is an angle is not defined for the rotation of J2. Does it means J2 does not have linearly independent motion?And the fourth equation of motion (for the second J=0), I can understand the theta 4 term being due to the torques associated with it's motion but I don't get the other term.
