The figure shows an arrangement in which four disks are suspended by cords. The longer, top cord loops over a frictionless pulley and pulls with a force of magnitude 90.4 N on the wall to which it is attached. The tensions in the shorter cords are T₁ = 56.7 N, T₂ = 37.1 N, and T3 = 8.16 N. What are the masses of (a) disk A, (b) disk B, (c) disk C, and (d) disk D?
