O2BCO4 is a four-bar linkage. O2 and O4 are fixed centers on a horizontal line 10 in apart. O2B is a link 5 in long oscillating about O2. O4C is a crank 2 1⁄2 in long which rotates about O4. BC is a connecting rod 11 1⁄2 in long. O2 is to left of O4. A link, EF, 6 in long, is pinned to O2B at E, 1 1⁄2 in from B. Another link, GF, 3 1⁄2 in long, is pinned to link BC, 4 in from C.

Model the following system by writing the two equations of motion for the double-pendulumsystem shown in the figure below. Assume the displacement angles of the pendulums are smallenough to ensure that the spring is always horizontal. The pendulum rods are taken to be mass-less, of length l, and the spring is attached a distance of d down the length of the rods.
