Answer Exercise 6.1.14 for the mass-spring chain in Exercise 6.1.4.
(a) Determine the equilibrium positions of the masses and the elongations of the springs when the external force is f = (0, 1, 1, 0)T. Is your solution unique?
(b) Suppose we only fix the top support. Solve the problem with the same data and compare your results.
