Figure 5-33 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 98 N on the wall to which it is attached. The tensions in the three shorter cords are T1 = 58.8 N, T2 = 49.0 N, and T3 = 9.8 N. What are the masses of (a) disk A, (b) disk B, (c) disk C, and (d) disk D?

Draw the force diagrams of each mass.
I am doing for the first two.|dw:1332083928654:dw|
The force equation for the first body is:
T=T1+m1g(Now put the given values and find m1)
For second body.
T1=T2+m2g
Now, do this for the other two bodies, put the given values and find the masses.
