tating shaft carries four masses 176.6 N, 137.3 N, 157 N and N at radii 5 cm, 6 cm, 7 cm and 6 cm respectively. The second, d and fourth masses revolve in planes 8 cm, 16 cm and 28 cm ectively measured from the plane of the first mass (at the left ). They are angularly located at 60°, 135° and 270° respectively Sured clockwise from the first mass lat th e nositive Kaxis!

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 60°, 135° and 270° 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
masses and midway between those of 3" and 4th masses.
Determine the magnitude of the masses and their respective
angular positions.
