Matlab 5

For the TSDA elements, should we calculate Qi, Qj or both?

You'll have to compute both, since you want to add the contribution of this TSDA to *both* bodies: each body "feels" a force due to the TSDA, and this force should find its way into the equations of motion in the Qi and Qj guys.

Specifically, Qi should be added to the RHS in the rows associated with body "i" (think how you assembled the Mass matrix and how the columns of Phi_q are [note that the columns of Phi_q become the rows in Phi_q^T]).  You do the same for body j.  In the end, once you have Qi and Qj it is just a matter of book-keeping.

I hope this helps.
