Horsepower vs Torque - A Simple Explanation

What's The Difference Between Horsepower & Torque? Why Is Peak Acceleration At Peak Power? https://youtu.be/cb6rIZfCuHI Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 Awesome Car Products: https://www.amazon.com/shop/engineeringexplained Which is better, horsepower or torque? Two words that are often stated in the car community, but often misunderstood. This video seeks to clarify the difference between the two, without silly analogies like "horsepower is how fast you hit the wall, torque is how far you take it with you" (which, by the way, is highly inaccurate). Torque is a force acting at a radius, while horsepower simply incorporates time into the equation. This video will discuss the differences, how each applies to internal combustion engines, how they relate, what peak torque and peak horsepower actually mean, and how to analyze torque and horsepower curves. Finally, what's more important for acceleration, a car with lots of power, or lots of torque? Let's get technical. With the context of an engine: Power = Torque x Angular Velocity. In imperial units, this translates to Horsepower = Torque x RPM / 5252. Engineering Explained is a participant in the Amazon Influencer Program. Don't forget to check out my other pages below!

7 Things You Shouldn't Do In an Automatic Transmission Car

Do you drive a car with an automatic transmission? 🚕 The interface of automatic vehicles is often simpler, and new drivers don't have to struggle with a seemingly unruly stick shift and clutch. But there are still some ways you can mess up your transmission. Here are 7 of the most dangerous mistakes you can make when driving an automatic! 📣 TIMESTAMPS: Don't shift from "drive" to "reverse" before your car stops moving 1:06 Never put your car in "park" before it stops completely 1:55 Don't put it in "neutral" at stop lights 2:56 Don't coast in "neutral" 3:53 Never “launch” your car from a standstill 4:44 Avoid keeping the gas tank on low 5:48 Do not let water get in the transmission 6:31 #automatictransmission #drivinghacks #drivingtips Music: https://www.youtube.com/audiolibrary/music SUMMARY: - If your brakes wear down, replacing them will cost you around $200. But by constantly shifting from "drive" to "reverse" while the car’s still rolling, get ready for damage that can run you at least $2,500. - When you throw it in “park,” a pin locks the transmission output shaft, which connects it to the wheels of your car. But if the car’s still rolling when you do this, either the locking pin or the output shaft may break or become eroded. - It's better to keep your car in "drive" than to switch it to "neutral" when stopped at a light. First of all, when your car’s in "neutral," you don't have as much control over it. So if you need to make some emergency maneuver, you may not be able to execute it in time. - Cars with automatic engines are designed in such a way that they save fuel even if the gear is in "drive." They simply cut the fuel supply when you're going downhill. - Plenty of drivers launch their cars all the time. This causes serious harm to the bands and clutches of the automatic transmission. When you shift, they use friction to move definite parts. - Ignoring the low fuel light may eventually cost you much more than just filling your tank up, especially if your car has an automatic transmission. - If water gets into the transmission, you're in big trouble. Even the smallest amount of water, just an ounce, can wreak havoc on your car’s transmission to the point that it needs replaced.

AWD versus 4WD SUV explained: Which is best?

Four-wheel drive versus all-wheel drive. Easy Select versus Super Select II. What does it all mean? If my inbox is anything to go by, there’s great uncertainty out there about all-wheel drive and four-wheel drive. In reality, it’s not that simple. Or at least, not clear-cut. Let’s clear a few things up: Firstly, four-wheel drive. Let’s define that, arbitrarily, as a system designed only for low traction surfaces, slippery underfoot, in which the drive to the front axles and the drive to the rear axles can be locked together at the same rotational speed, using Fred Flintstone engineering. In other words, the front and rear prop shafts are mechanically locked to rotate at the same rate. All-wheel drive: Let’s define that arbitrarily as a system designed to drive all four wheels, either continuously or occasionally, but with the front and rear prop shafts able to turn at different rates. And that means you can use all-wheel drive on high-traction surfaces (like sealed roads; dry bitumen). The big difference: When a vehicle drives on a curve, the front end and the rear end follow different paths. Therefore, the front and rear ends travel different distances. Therefore, on a high-traction surface, the front and rear prop shafts need to spin at slightly different rates. On a low-traction surface, the tyres can slip a bit, if the front and rear prop shafts are locked. But if you put a vehicle into four-wheel drive mode (prop shafts locked in unison) and you drive on a high-traction surface, on a curve, you will break something - at least, you open this door, and warranty will not cover you because that’s technically abuse. So - all-wheel drive vehicles have some sort of sophisticated coupling between the front and rear prop shafts - either a differential, or a viscous coupling, etc, that allows this relative rotation. They’re more sophisticated, and therefore, more expensive. Most all-wheel drive SUVs have a four-wheel drive mode, usually engaged with a ‘lock’ or ‘4WD lock’ button, or sometimes a rotating switch. Typically you engage that to get through some mud or soft sand - whatever. In the snow. But not for driving on bitumen - if you know what’s good for you. I’m John Cadogan. I hope this helps.

Best Fight Scenes: Louis Fan

Louis Fan Siu-Wong is a Hong Kong martial artist most recognizable as the northerner Jin Shanzhao in the film “Ip Man”, a master of the style of Kung Fu called Shaobeiquan. His performance won him a nomination for Best Supporting Actor at the 28th Hong Kong Film Awards. Besides portraying that same character again in “Ip Man 2”, he also played Ip Tin-chi in “The Legend is Born: Ip Man”. But many also attribute him to his starring role in the campy martial arts cult film “Riki-Oh: The Story of Ricky”, a live-action movie adaptation of the manga of the same name, which came out over a decade before the first Ip Man film. Trained in Wushu and gymnastics, he is a talented martial artist and actor. Here's a compilation of my favorite Louis Fan fight scenes. List of movies featured in order of appearance: 1. Ip Man 2. The Legend is Born: Ip Man 3. Kung Fu Jungle 4. Master of Zen 5. The Death Games 6. Shadow Mask (2001) (Alan Chan Yiu-Lun) 7. (outro) Riki-Oh: The Story of Ricky Other notable films/television series include Righting Wrongs, Immortal Story, Once a Cop, Connected Lovers, Butterfly Lovers, Kung Fu Chefs, Give Love, On His Majesty’s Secret Service, Just Another Pandora’s Box, Ip Man 2, Future X-Cops, Flirting Scholar 2, A Chinese Ghost Story, The Flying Swords of Dragon Gate, Choy Lee Fut Kung Fu, Wudang, The Monkey King, The Bounty Hunter, Demi-Gods and Semi-Devils, Bodyguards and Assassins, and The Bride with White Hair.

What's the difference between all-wheel drive and 4-wheel drive?

4WD is not on all the time, under normal conditions, only the rear wheels drive the vehicle forward, while the front wheels spin freely. To activate a modern four-wheel drive system, the driver has to push a button or pull a lever to engage it. But four-wheel drive isn't meant to be on all the time so you have to know when to turn it on and when to turn it off.

AWD is on all the time, and mostly used in cars, and the computer manages the system. Just going down the highway, the system will send most of the power to the rear wheels, for maximum fuel efficiency, if the road condition changes, such as rain or snow, the system adapts and evenly distributes the power evenly to all 4 wheels, so you have maximum drive grip, with little to no chance of wheel spin.

2WD Cars are less complex than those with AWD or 4WD, and their simpler drivetrains mean improved fuel economy in the long run.

In general, cars equipped with 2-wheel drive get better gas mileage than models that use all-wheel drive or 4-wheel drive.
