Question 1034116
.
Hi! My homework question is...  A pinion gear with 10 teeth is driving a spur gear with 40 teeth. 
The spur gear is rotating at 160 rpm, What is the speed of the pinion gear?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
{{{R[pinion]*T[pinion]}}} = {{{R[spur]*T[spur]}}},


where R is rpm and T is number of teef.


If so, then {{{R[pinion]*10}}} = {{{160*40}}}.


Solve for {{{R[pinion]}}}.
