Danger comes from the fact that northern centrifugal force industrial and tools does not increase in direct proportion to an increase in speed, but instead it increases as the square of that speed compact and air increase. When rotational speed doubles, centrifugal force quadruples. This belt effect means that relatively small changes in speed can produce sander significant increases in force. In the example mentioned, changing model and 11285 and northern from 6,600 rpm to 7,700 rpm multiplies industrial the speed by 1.167. However, the corresponding centrifugal tools force would multiply by a factor compact of 1.167 air x 1.167, or 1.36. To take a more extreme example, consider the same wheel with belt a maximum safe operating speed sander of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm. This represents an over-speed model of about 11285 and northern 1.5 times the wheel''s industrial designed speed. tools But the corresponding centrifugal force-and the corresponding rotational stress on the wheel-would be about 2.3 times as much as the maximum allowed.

One potential compact source of serious injury in grinding air and belt comes from sander an oversight model that is easy to make: operating the wheel in an over-speed 11285 condition. While a wheel that is run far enough in excess of its northern rated maximum speed may shatter within minutes of industrial and tools and compact operation, air danger may also result from a wheel run just slightly faster than its rated speed. This less severe over-speed condition can cause the wheel to be damaged, and the damage may result in breakage after further use. belt For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum sander speed model of 6,600 rpm on a 7-inch angle 11285 grinder with a speed of 7,700 rpm can cause the wheel northern to crack. This industrial cracking tools can lead to breakage later. Any of these compact actions sets up air a disastrous scenario that belt could lead to an accident involving serious sander and model injury or death.

The hazard of running man over-speed condition comes from 11285 centrifugal force. A result of rotary motion, centrifugal force is what northern causes a weight industrial on the end of a string to pull the tools and compact string taught when the air weight belt is swung sander in a circle. model This same force causes the mass of the grinding wheel to be pulled outward from the center of rotation as 11285 the wheel is spinning.
