Answer to Question #291504 in Mechanical Engineering for haziq

Question

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 135º 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.

calculate the magnitude of balance masses

.
