Q4:-A rotating shaft carries four masses 176.6 N, 137.3 N, 157 N and 117 N at radii 5 cm, 6 cm, 7 cm and 6 cm respectively. The second, third and fourth masses revolve in planes 8 cm, 16 cm and 28 cm respectively measured from the plane of the first mass (at the left end). They are angularly located at 60o , 135o and 270o respectively measured clockwise from the first mass (at the positive x-axis). The shaft is dynamically balanced by two masses both located at 5 cm radii and revolving in planes midway between those of 1st and 2 nd masses and midway between those of 3rd and 4th masses. Determine the magnitude of the masses and their respective

Question
Q4:-A rotating shaft carries four masses 176.6 N, 137.3 N, 157 N and
117 N at radii 5 cm, 6 cm, 7 cm and 6 cm respectively. The second,
third and fourth masses revolve in planes 8 cm, 16 cm and 28 cm
respectively measured from the plane of the first mass (at the left
end). They are angularly located at 60o
, 135o
and 270o
respectively
measured clockwise from the first mass (at the positive x-axis).
The shaft is dynamically balanced by two masses both located at 5
cm radii and revolving in planes midway between those of 1st and
2
nd masses and midway between those of 3rd and 4th masses.
Determine the magnitude of the masses and their respective
angular positions.
