To improve the acoustics in an auditorium, a sound reflector with a mass of 200 kg is suspended by a chain from the ceiling. Suppose that the mass of the chain is not negligible, but is 10.0 kg. Let's find the forces at the ends of the chain. Figure Y = NTV We 41 ~ → WC 1 of 3 Alternative Solution: An alternative procedure is to draw a free-body diagram for the composite object c and the chain together (Figure 3). The two forces on this composite object are the upward force T₁ at the total weight, with magnitude 1960 N +98 N = 2058 N. Again, we find that T₁ = 2058 N. Note that w method; we still need a separate free-body diagram for one of the objects. REFLECT When a composite object can be divided into two or more component parts, there are usually s solutions. Often, the calculations can be simplified by a clever choice of subsystems. Also, solving a probl alternative ways provides a consistency check that's useful in finding errors.
