5 (b) 5 (a) Figure Q5(a) shows the orientations of masses mp=500 g, mo=400 g and ma=600 g attached on a rotating circular plate at radial distances fp=250 mm, ro=200 mm and rr=150 mm respectively in a single plane. It is required to balance the plate by adding a single mass ms at a radial distance of rs=100 mm. A Determine the magnitude and orientation of the balancing mass using the graphical method.

The masses are located at the following radii: Figure Q5(b) (Not to scale) ma = 3 kg; ra= 80 mm mg = 2 kg ; = 120 mm B = Masses me and my are to be placed at planes M and N respectively to produce static and dynamic balance of the shaft system. Using graphical analysis, determine the magnitudes and orientations of the masses mu and me to be placed in two planes at radial distances ru=50 mm in plane M and n=90 mm in plane N respectively.
