# What is the difference between torque and horsepower in automobiles?

Answer By Karl Brauer, Editor in Chief, Edmunds.com While horsepower is often considered when shopping for a vehicle, what about that "other" engine rating: torque…? Specifically, what are the differences between horsepower and torque? If you flip through the pages of any automotive publication, you'll notice that these two measurements are commonly listed under vehicle specifications. And while the average car enthusiast knows that both horsepower and torque play a role in performance, most of them don't understand exactly how or why. Let's begin by explaining the technical difference between the two. Horsepower is defined as the amount of energy required to lift 550 pounds, one foot, in one second. From this definition you can see that the components of horsepower are force, distance and time. Distance and time are self-explanatory but force, specifically a twisting force, is what torque is all about. Remember that the initial energy that moves a car forward starts in the combustion chamber in the form of an explosion. This explosion forces a piston (or group of pistons) down in a straight line, which pushes on a connecting rod and turns the engine's crankshaft. It's this turning crankshaft where the twisting force of torque initiates. From there the force is carried through a flywheel, transmission, driveshaft, axle(s) and wheel(s) before moving the car. The measurement of torque is stated as pound-feet and represents how much twisting force is at work. If you can imagine a plumber's pipe wrench attached to a rusty drainpipe, torque is the force required to twist that pipe. If the wrench is two feet long, and the plumber pushes with 50 pounds of pressure, he is applying 100 pound-feet of torque (50 pounds x 2 feet) to turn the pipe (depending on the level of rust, this may or may not be enough torque). As you may have noticed, this measurement of torque does not include time. One-hundred pound-feet of torque is always 100 pound-feet torque, whether it is applied for five seconds or five years. So, if you want a quick answer to the difference between horsepower and torque, just keep in mind that horsepower involves the amount of work done in a given time, while torque is simply a measurement of force and is thus a component of horsepower. To see how torque and horsepower interact, imagine your favorite SUV (everyone has one of those, right?) at the base of a steep hill. The engine is idling and the gear lever is in the "Four-Low" position. As the driver begins to press on the throttle, the engine's rpm increases, force is transmitted from the crankshaft to each wheel, and the SUV begins to climb upward. The twisting force going to each wheel as the vehicle moves up the hill is torque. Let's say the engine is at 3,000 rpm, the gear ratio is 3, and the vehicle is creating 300 pound-feet of torque. Using the following formula, we can calculate horsepower: Take the torque of 300 multiplied by a shaftspeed of 1000 (3000 rpm divided by a gear ratio of 3) for a total of 300,000. Divide 300,000 by 5,252 and you get 57.1 horsepower that the SUV is making as it begins to ascend the hill. It is interesting to note that, since 5,252 is used to calculate horsepower by way of torque and shaftspeed, it is also the number in the rpm range at which torque and horsepower are always equal. If you were to view the horsepower and torque curves of various engines, you would notice that they always cross at 5,252 rpm. So now we have a technical understanding of how torque interacts with horsepower, but let's move beyond that to some real-world examples. For instance, we all know that a car moves from a dead stop in 1st or low gear, yet as the car's speed increases, the gears must be moved up through 2nd, 3rd and 4th to maintain acceleration. This is because at low speeds the transmission's gears work to transmit maximum torque from the engine to the wheels. You want this because it takes more force, or torque, to move a vehicle that is at rest than it does to move a vehicle in motion (Newton's 1st Law). At the same time, once a vehicle is underway, you want less torque and more horsepower to maintain a high speed. This is because horsepower is a measurement of work done and includes a time element (such as wheel revolutions per minute necessary to maintain 75 mph). Since entire books have been written on the concepts of horsepower and torque, it's not realistic to try and cover them fully in a single column. Finally, let me leave you with my favorite phrase about the relationship between horsepower and torque: Horsepower is what you read about, torque is what you feel.

# What is the difference between SR22 and liability automobile?

SR22 Insurance and Auto Liability There is no difference at all other than that you have requested the SR22 filing. An SR22 Form is proof of Financial Responsibility for… the State that you are now in compliance with the states Financial Responsibility Laws. An SR22 filing is usually required due to a drivers having already been cited for a prior offense. The SR22 is required to prevent the drivers license from being suspended or to re-instate it after a suspension. It may or may not be a high risk driver requiring the SR22 Filing. Most companies add no points against you because of the SR22. Points however may be added due to the actual ticket or violation that prompted the SR22 requirement in the first place but not for the SR22 itself. Some companies will impose a one time servicing or maintainance fee for filing the form. An SR22 filing requirement in and of itself in no way effects whether a driver is more likely to have an accidental loss.

# What is the Difference between average and median?

If I remember correctly, there are four types of averages: mean: this is what most people think of as the "average" of a bunch of numbers. The mean of 2 and 8 is 5. mode: …this is the number that occurs most in a set of numbers. The mode of 2, 2, 2, 5. and 9 is 2. median: this is the number that occurs in the middle of a set of number when they're arranged from lowest to highest. If there are two middle numbers, take the mean of them. The median of 1, 2, 3, 4, 5, 6, and 7 is 4. The median of 1, 2, 3, and 4 is (2 + 3) / 2, or 2.5. range: this is the biggest number in a set minus the smallest number. The range of 1, 4. 9, and 12 is (12 - 1), or 11. I think that's all correct. Hope that helps. Edit: All definitions are correct except that the range is not an average, it is a measure of spread. To be considered along with more complicated stuff like inter-quartile ranges, standard deviations and so on. Edit2: In analysis there are several other ways to calculate the "average": Range Average is the mean of the lowest and highest values. Quartile mean is taking the center most 50% of the values adding them up and dividing by the number of them. Quartile Range Average is adding the 1st and 3rd quartiles and dividing by two. (the 1st quartile is the value that is greater then 25% of the values and less then 75% and the 3rd quartile is greater then 75% and less then 25%). "Bucket Modes" can also be calculated for an average. A bucket mode is calculated by finding the mode not of a single value but over a range of values or the range of values that combined have the greatest occurrence. Any method can also be calculated be excluding data points. The most common is to exclude outliers. Outliers can be defined as any of the top and or bottom data points that lie in the top or bottom x% (i.e. exclude the top 3% or the top 15%). Outlier can be defined as being over x deviations away from a central point where x is typically 3, 2, or 1.5 but can actually be any number). In some analysis the number crunchers can and often do through out any numbers that they suspect are questionable, don't look right, or they do not want to use. In statistics they also use a term "Expected Value" to refer to an average. Depending on the dispersion of the data the method of calculating the Expected Value changes. Often, this becomes a calculus or differential problem. The basic idea is the that the expected value is calculated to make the sum of the differences between the data points and the Expected Value to be the smallest. This is not an exhaustive list. When modeling the world, analysis can create various schemes for defining a way to calculate average. The idea is to create a way to calculate a number that will express the central tendency of the data points or to come up with a value that can be used to correctly estimate the data points in calculations.

# What is the average mileage lifespan of a Chevy S10 and does its year make much of a difference in reliability?

My 1993 2.8 has 154000 and still going strong. It depends on your maintenance habits. Keep the oil and oil filter changed every 3000 miles and keep carb or fuel injectors clea…n. Maintenance is the life of any vehicle! I've got a 1985 Chevy S10, 2.8L V6, I bought it back in '85 and kept up on the maintenance and it still runs great! 178,000 miles. And of course you get the normal (minor) repairs as it gets older but as long as you keep it in good condition they should last quite a while! I have a 1989 Chevy S-10 2.5L 4 cylinder which I bought when it had 45,000 miles. It now has 199,566 miles and is still running strong. I do regular minor maintenance like change oil, replace sparkplugs and/or sparkplug wires, etc. I have also repaired the brakes, alternator, and exhaust system over the years. But, I have never had a major problem with the transmission or engine. I believe with with proper maintanance, the truck can last forever.
