As your arms are moving in a circle, the tension in your arms not only needs to balance
the weight of your arm, but also needs to generate the centripetal acceleration that keeps your
arms in a circular track. Keep in mind that the centripetal acceleration acts at the c.o.g. of your
arm and points straight inward along the x-direction towards the rotation axis and not upward
along your arm.
maybe you mean revolutions PER minute (RPM) which is the number of revolutions (rotations of 360 degrees) that take place in a minute of time. speed is a measure of change in position (in this case change in angle of a component) for a given time period.
A 78 is a gramophone record played at 78 revolutions per minute.
Max RPM is the term for maximum revolutions per minute of a car engine. Red line is another term for max rpm.
It is the number of strokes (forward and back) the piston makes in one minute. For radial (turbine) and rotary steam engines, it is the number of revolutions per minute.
rpm is REVOLUTIONS PER MINUTEthis is how many times something revolves a complete cycle in one minuteAnswerRPM stands for REVOLUTIONS PER MINUTE. This is a measure of how many times your tires revolve in a single minute. Answerrpm means revolutions per minute Answerrpm measures the exact number of times the tire rotates in a single 60 seconds
revolutions per minute - the number of times the turntable goes round in 1 minute there were 4 speeds 16, 33, 45 and 78
The rev counter works by counting the number of revolutions per minute of the engine. It is more often referred to as the tachometer and the numbers are multiplied by 1,000. If the gauge reads 18, that means that the engine is turning at 18,000 revolutions per minute.
revolutions per minute - the number of times the turntable goes round in 1 minute there were 4 speeds 16, 33, 45 and 78
A digital tachometer measures the speed of objects. They measure the rotations of an engine shaft in a car and then record the number of revolutions per minute on a dial.
The number referred to the speed of the turntable in revolutions per minute (RPM). Vinyl records were recorded at various RPM. 33 1/3, 45, and 78
RPM stands for Revolutions Per Minute so, in short, RPM is the number of revolutions that the generator shaft turns in one minute. It seems obvious that the question is really trying to understand RPM vs frequency in Hertz. To understand this, you need to know the number of poles in the rotating and/or stationary magnetic field. In a two pole generator, for instance, an RPM of 1800, or 30 RPS (Revolutions Per Second), yields 60 Hertz power. In a eight pole generator, for instance, an RPM of 450, or 7.5 RPS, yields 60 Hertz power. The equation is simple... FHertz = SRPM / 60 * PNumber of Poles
Dynamic stability is the property of retaining almost the same number of revolutions per minute when the mechanical load on the shaft is connected or diconnected.
