You can also relate this to the car crank shaft speed , and it is measured in Revolutions Per minute =RPM's. faster your crank shaft rotates (RPM's), the faster your pistons travel up and down the cylinders, thus the faster your car will go. Hope this was what you were looking for...
Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft)/ 60 Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shâft3).
CRITICAL SPEED CALCULATION Thr RPM which numericlly concide with the natural frequency of transverse Vibration of the shaft is Known as critical speed . Critical speed is a function of mass of rotating component and Stiffness of its material . F=stiffness of rotating component m=mass of the same
== distance x time== speed ==
780 rpm
1750 x 8/17 = 823.5 rpm
P0720 - Low Output SPD Sensor RPM Above 15 MPHThe relationship between the Output Shaft Speed Sensor and vehicle speed is not within acceptable limits. P0720 - Low Output SPD Sensor RPM Above 15 MPHOutput shaft speed is less than 60 rpm with vehicle speed above 15 mph (4-speed auto. trans. only).
Taco generator is the one which is attached to the shaft of big rotating machine to find out its speed. It converts the the rpm in to voltage i.e. the voltage generated in the small generator is directly proportional to the speed of the shaft to which it is attached meter attached to this generator is graduated in rpm instead of volts .
power = torque * rpm
By using a simple formulae: f=np/60 where f= frequency, n is the number of pair of poles and 60 is in seconds that motor is turning. So a 4 pole motor with a frequency of 50 hertz will run at 1500 rpm. By manupilating the formulae: n= 50 multiplied by 60 devided by 2 therefore n= 1500rpm. The formula 120xFrequency/poles gives synchronous speed not actual shaft RPM. Induction motors must run at a certain % slip to obtain torque, so a 4 pole motor running at 50hz would be 120x50/4 = 1500 rpm, at 4% slip (operating speed) actual shaft RPM or rated speed would be 1440 RPM.
You must buy a bicycle computer and attach it to your bike. They can calculate various things- speed, distance, RPM, time, tempertature, altitude, speed increase or decrease
A tachometer is a device that measures the rotation speed of a shaft or disk, as in a motor of other machine. In automotive use, it is used as a gauge showing the speed (RPM) of the engine shaft that is driving the transmission, usually in thousands of rotations per minute. Too high a tach speed can damage the engine.
u do distance/ time= speed
