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. This represents an over-speed of about 1.5 times the wheel's designed speed.
