This is not obvious - in fact, I'd argue that carrying around the extra dimension in the shape makes it more difficult to interpret the arrays. AFAICT, the main reason for doing so is so that thehstack-ing works when constructing the system matrix. Instead of introducing the extra dimension at the beginning of the processing, I'd vote for simply adding a "dummy" dimension for the hstack, i.e. something like:
unknown_forces=np.hstack((Unit_BD[:,np.newaxis],Unit_BE[:,np.newaxis],np.eye(3)))

Just a quick ping on this one@h2o-DS - WDYT? If you don't have the bandwidth to make these updates but are not opposed to them, I'd be happy to push them up!
Fixed some formatting and extended the static equilibrium tutorial to include np.linalg.solve()
