Danger comes from the fact that centrifugal force chicago and pneumatic does not increase in direct proportion to an increase in speed, mini but instead it increases as the square of that speed increase. When rotational speed random doubles, centrifugal force orbital quadruples. This effect means that relatively small changes in speed can produce significant increases sander in force. In the example mentioned, changing from 6,600 kit rpm to 7,700 rpm multiplies the speed by model and cp7200s 1.167. However, chicago the corresponding pneumatic centrifugal mini and random force would multiply by a factor of 1.167 x 1.167, or 1.36. To take a more extreme orbital example, consider sander the same wheel with a maximum safe operating kit and model speed of 6,600 rpm run on cp7200s a 5-inch right angle grinder chicago at 10,000 rpm. This represents an over-speed pneumatic and mini of about 1.5 times the wheel''s designed speed. But the corresponding centrifugal random and orbital and sander and kit and model and cp7200s force-and the corresponding rotational stress on the wheel-would be about chicago and pneumatic 2.3 times as much as the maximum allowed.

One potential mini source random of orbital serious injury in grinding comes sander from an oversight that kit is easy to make: model and cp7200s and chicago and pneumatic operating the wheel in mini an over-speed condition. While a wheel that is run far enough in random excess of its rated maximum speed orbital and sander may shatter within minutes kit of operation, danger may also result from a wheel run just slightly faster than its rated speed. model This cp7200s less severe over-speed condition can cause the wheel to be damaged, and the chicago damage may result in pneumatic breakage after mini further use. For example, random operating a reinforced, orbital 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with sander a speed kit of 7,700 rpm can cause the wheel to crack. This cracking can lead to breakage later. Any of these actions sets model up a disastrous scenario that could lead to an accident involving serious injury or death cp7200s.
