Mar 15 2003 · In the example mentioned changing from 6 600 rpm to 7 700 rpm multiplies the speed by 1.167. However the corresponding centrifugal force would multiply by a factor of 1.167 1.167 or 1.36. To take a more extreme example consider the same wheel with a maximum safe operating speed of 6 600 rpm run on a 5-inch right angle grinder at 10 000 rpm.
