Solve Problem on Balancing of masses rotating in different planes by using graphical method.

A shaft carries four masses in parallel planes A, B, C, D in this order along its length. The masses at B and C are 18 kg and 12.5 kg respectively and each has an eccentricity of 60 mm.
The masses at A and D have an eccentricity of 80 mm. The angle between the masses at B and C is 100° and between masses at B and A is 190° , both being measured in the same direction. The axial distance between plane A and B is 100 mm and between B and C is 200 mm. If the shaft is in complete dynamic balance determine :
1. The magnitude of masses at A and D
2. The distance between planes A and D
3. angular position of mass D

Amazing lecture!!
If you have time, please create playlist naming different topics rather than just 'Dynamics of Machinery' .
It will surely increase your reach
