Why is the relationship between torque horsepower and RPM not linear In automobile terms.?

It is, Horsepower = Torque x RPM, but Torque is not constant across the rev range of an engine. For gasoline engines, there is generally very little torque at low rpms, generally flat torque across the middle rpms, and then a drop off as the engine starts spinning too fast for complete combustion. Electric engines, on the other hand, start off with maximum torque and decrease with higher engine speed. So, the short answer to your question is that it's a direct relationship between horsepower and torque, but the variation in the torque curve across the rpm range makes the resultant horsepower curve vary too. (If your question was really why does torque vary with rpm, simply stated it's because engines have varying efficiencies at different speeds.)

What is the speed in RPM of a ceiling fan?

The speed of a ceiling fan is typically measured in revolutions per minute (RPM). A typical ceiling fan may have speeds ranging from around 50 to 200 RPM on the low setting, and up to 200 to 300 RPM on the high setting.


What is the rpm of the earth?

RPM = revolutions per minute 0,000694rpm -> considering that the Earth rotates in 24 hours 0,000696rpm -> considering that the Earth rotates in 23h and 56 minutes (which is the real time in which the Earth makes 1 revolution) therefore in general its .00069


What is the mean of RPM in the Ceiling Fan speed?

The mean rotational speed of a ceiling fan is typically measured in revolutions per minute (RPM). The average RPM of a ceiling fan can vary depending on the specific model, but it is commonly around 150-250 RPM for normal operation.


How much rpm for 12 volt ac motor?

The formula for RPM is, RPM = Hz x 60 x 2/# of poles the motor has. To answer this question more information needs to be stated.

At what speed should i shift gears on 2002 sportster 1200C?

I have a 2001 sporster. I usually shift at or alittle above 3000 rpm. Any thing lower puts my rpm at or under 2000 in the next higher gear, which makes my engine labor. I use my tac to shift and have never noticed the mph.

When should you shift in a 1984 corvette with RPM?

Red-line is at 4200 RPM and peak torque of 290 pounds-feet is at 2800 RPM.


How do you know where to shift your gear while riding?

To know when to shift gears while riding, pay attention to the engine's RPM (revolutions per minute) and the bike's speed. Shift up when the engine reaches a higher RPM, typically around 2,500 to 3,000 RPM for most motorcycles, to maintain optimal power without straining the engine. Conversely, shift down when the RPM drops too low, usually around 1,500 RPM, to avoid stalling. Additionally, listen to the engine's sound and feel the bike's response to help determine the right moments to shift.


How Shift gear RPM 13 speed eaton fuller transmission?

Keep rpm between 1400 to 1600


What RPM range should you use to change gear in my Toyota MR2?

If you are looking to max your gas mileage, shift earlier like around 2500-2800 rpm. To make your car sound cool, I shift at 4000 rpm, but it will use more fuel


What will happen if I don't shift when shift light flashes?

You will use more gas due to the higher RPM. The shift light is to help you to save on gas milage.


What is the ECT button for on the center console for 99 elantra?

It provides a little more power by changing the transmission shift times to a more aggressive setting. For instance if in normal mode it may shift at 3,500 rpm. With the ECT in power mode, it would probably shift at 4,000 rpm or 4,500 rpm. Setting the ECT to power will however lower your gas mileage.


What RPM do you shift a Dodge 3500 6 speed?

1600-2100 rpms


At what RPM do you shift on a motorcycle?

It depends on the motorcycle. I have a 96 buell s2t and ideal shifting rpm is about 4000. anywhere before the red on your tac


What number do you shift on?

Depends on what you're trying to accomplish, and what you're driving. But most of the time anywhere from 2500 rpm and 3500 rpm is a safe bet.
