A shaft carries four masses
in parallel planes A, B, C and
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 that between the
masses at B and A is 190°,
both being measured in the
same direction. The axial
distance between the planes
A and B is 100 mm and that
