A pendulum consisting of three masses is shown below. The middle mass M is fixed at the midpoint of a long string, the ends of which are tied to masses m each. The strings hang over two massless pulleys (located at the same height). The pulleys are a distance 21 apart and have negligible size. Assume that the mass M is constrained to move in a vertical line midway between the pulleys. Let 8 be the angle the string from mass M makes with the horizontal. Find the Equation of Motion for 8. ●
