Three rotating masses, A= 14 kg, B =11 kg and C =21 kg are attached to a shaft with center of gravity 275 mm, 400 mm and 150 mm from the shaft axis. The angular position of B and C are 60° and 135 measured in the same direction from A. The distance between plane AB is 1.35 m AC is 3.6 m and plane B is between AC. Two balance masses are to be fitted between plane A B and BC and the center of gravity of each mass is 225mm from the shaft axis.

Transcribed Image Text:Three rotating masses, A= 14 kg, B =11 kg and C
=21 kg are attached to a shaft
with center of gravity 275 mm, 400 mm and 150
mm from the shaft axis. The
angular position of B andC are 60° and 135°
measured in the same direction
from A. The distance between plane AB is 1.35 m,
AC is 3.6 m and plane B is
between AC. Two balance masses are to be fitted
between plane A B and BC
and the center of gravity of each mass is 225mm
from the shaft axis.
