Q) A rotating shaft carry four unbalanced masses 12kg, 8kg, 10kg and 6kg at radii 4cm,5cm,6cm and 5cm respectively. The 2nd,3"and 4th masses in plane 7cm, 16cm and 30cm respectively measured from the plane of the first mass and angularly located at 50°, 150° and 270° respectively measured counterclockwise from the first mass locating from this mass end of the shaft. The shaft dynamically balanced by two masses both located at 4cm radii and revolving in plane mid-way between there of 1tand 2n masses and mid- way between these of 3rdand 4"masses.Determine graphically the magnitude of the masses and their respective angular position. 278 16cm 30cm
