A pulley's revolutions is measured in rpms if the it is driven by a motor. Otherwise, revolutions describes the amount of revolutions the pulleys will make in tandem. In order to find the revolutions of the driver pulley, plug in the appropriate values: (Diameter of driven pulley) x (Revo...
Calculate the belt velocity by multiplying the circumference of the pulley by the speed of the pulley. For example, the drive pulley has a circumference of (Pi)(D2). This equals 2(Pi). The speed of the pulley is 1,800 rpm. Multiplying these equals 11,304 inches per minute. Divide thi...
Jp2= inertia of idler pulley (provide by manufacturer, or calculate) (kgm2) Jl= inertia of load (kgm2) Although we assumed above that the drive and idler pulleys have the same radius, their inertias may be slightly different, since the drive pulley is toothed and, therefore, has a slight...
Using a smaller pulley on a high revving engines can cause component failure from extreme speeds.Alternators are only good for about 15,000 continuous RPM's, the lower the alternator RPM's the longer your alternator will last. how to calculate your alternators RPM's you measure your crank ...
How to Calculate Drill Speed Speed refers to the revolutions per minute (RPM) of the drilling machine spindle. For drilling, the spindle should rotate at a set speed that is selected for the material being drilled. Correct speeds are essential for satisfactory drilling. The speed at which a ...
Average speed is a crucial factor to learn the time it takes to complete a journey. Average speed is essentially a mechanism that helps us calculate the rate of travel time and distance. It is evident that the speed keeps on changing in the journey, making finding the average speed more im...
Calculate the weight in newtons of a person who has a mass of 50 kg. If you doubled the mass of the hanging weight, by what factor would you theoretically have to increase the speed of the stopper? A 2.55 kg briefcase is sitting at rest on a level...
To calculate the lining size: 1. For the width of the lining, subtract 2″ from the width that you want the finished shade to be. In our example, the shade width is 36″ wide so the lining width will be 36″ – 2″ = 34″ wide. ...
To calculate the equivalent resistance divide the battery’s full charge voltage by the current draw you measured above the result is the number of ohms of resistance you need to simulate your motors. Make sure the resistor you use can handle the load otherwise it will overheat and burn up....
With the AC motors that have been preferred for the last 20 to 25 years, the principles are the same but the calculations aren’t as simple. There are several different types, so talk with the motor maker, if needed, to learn how to calculate torque and actual power ...
