A shaft carries a weigh (W) at the centre. The (C G) of the weight is displaced
Question:
A shaft carries a weigh \(W\) at the centre. The \(C G\) of the weight is displaced by an amount \(e\) from the axis of the rotation. If \(\mathrm{y}\) is the additional displacement of the \(C G\) from the axis of rotation due to the centrifugal force, then the ratio of \(y\) to \(e\) (where \(\omega_{c}\) is the critical speed of shaft and \(\omega\) is the angular speed of shaft) is given by
(a) \(\frac{1}{\left[\frac{\omega_{c}}{\omega}\right]^{2}+1}\)
(b) \(\frac{1}{\left[\frac{\omega_{c}}{\omega}\right]^{2}-1}\)
(c) \(\left[\frac{\omega_{c}}{\omega}\right]^{2}+1\)
(d) \(\frac{\omega}{\left[\frac{\omega_{c}}{\omega}\right]^{2}-1}\).
