Question

The figure below 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 80 N on the wall to which it is attached. The tensions in the shorter cords are T1 = 45.0 N, T2 = 37.3 N, and T3 = 7.7 N.

What are the masses of each disk?
(a) kg (disk A)

(b) kg (disk B)

(c) kg (disk C)

(d) kg (disk D)

Answer 1

There is zero probability you can get help on this without a diagram.
