Question

Which term defines the coefficient of fluctuation of speed of a flywheel in terms of angular speeds?​

TuteeHUB · Accepted Answer

$\frac{{\left( {{w_1} + {w_2}} \right)}}{{\;\left( {{w_1} - {w_2}} \right)}}$

TuteeHUB · Answer

$\frac{{2\;\left( {{w_1} - {w_2}} \right)}}{{{w_1} + {w_2}}}$

TuteeHUB · Answer

$\frac{{{w_1} + {w_2}}}{{2\left( {{w_1} - {w_2}} \right)}}$

TuteeHUB · Answer

$\frac{{{w_1} - {w_2}}}{{2\left( {{w_1} + {w_2}} \right)}}$
