Then MATLAB simplify worked. I think I have everything figured out, thanks for all the help! Mar 15 comment Modeling a two-mass, spring, damper system @RetardedPotential This is the transfer function I'm getting for ${X}_{2}$. I have no idea how I can simplify this d.pr/i/cQUF. I'm using Mathematica for the algebra. Mar 14 comment Modeling a two-mass, spring, damper system I've editing the original question to add my differential equations.

Thanks so much for taking your time to help me!

However, I have no textbook to look in for help. This problem is for an applied math class where we are supposed to write a MATLAB function to solve the truss. The professor just assumes that we know how to do this. Nov 16 comment Solving a statically indeterminate truss @DavidZaslavsky Sorry about that. I'm not really looking for a direct answer to the homework question, but more of just which method to use to solve a statically indeterminate truss. I've edited my question to make this more clear.
