If the eccentricity of a disc of mass ‘m’ rotating on a shaft is given as ‘e’ then the correction mass ‘mc’ at radius ‘r’ will be
1
\({m_c} = \left( {\frac{e}{r}} \right)m\)
2
\({m_c} = \left( {\frac{r}{e}} \right)m\)
3
\({m_c} = \left( {\frac{m}{{e\; \times \;r}}} \right)\)
4
\({m_c} = {\left( {\frac{e}{r}} \right)^2}m\)
