A sphere of coefficient of linear expansion `alpha`, mass 'm' and radius 'r' is is spinning about an axis through its diameter with an angular velocity `'omega'` when it is heated such that its temperature increases by `Deltat`, the angular velocity becomes

`omega(1+alphaDeltat)^(2)`

`omega/((1+2alphaDeltat))`

`omega(1+alphaDeltat)`

`omegaalphaDeltat`
