A sensor in the transmission, measures the output shaft speed.

rpm goes up and does not change gear below 60

A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.

Laser tachometer are instruments used to measure the rotation speed of a shaft or disk, as in motor or other machine. They usually display the revolutions per minute (RPM) on a calibrated analogue dial or digital display.

Its the gear that connects the speed sensor shaft to the transmission

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).

To calculate the stresses to the shaft.

== distance x time== speed ==

780 rpm

1750 x 8/17 = 823.5 rpm

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 .

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).

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

yes

u do distance/ time= speed
