I think horse has a lot of torque, but only 1 horsepower due to "rpm" Horsepower is basically how much work you can get done in a certain time period. Horsepower vs. torque When purchasing a new car, the crib sheet includes two output numbers with the engine: horsepower and torque. Torque is the measure in foot-pounds (ft.-lbs.) Power describes how fast energy is exchanged; a use of energy divided by how long it takes to use that energy. As born2bwire said, 1 horsepower is the ability to raise 550 pounds of mass 1 foot in 1 second, so it is a set number, where as horses are more varied in their strength. While it is true that the maximum output of a horse is around 15 horsepower, when you average the output of a horse over the course of a work day it ends up being around a horsepower. It’s a common misconception that one horsepower is equal to the peak power production of a horse, which is capable of a maximum of around 14.9 horsepower. Needless to say the team won, the problem was the car couldn't transfer all the force to the pavement, and when the wheels lost traction it was all over. All Rights Reserved. Horsepower is a unit of power. Somewhat related, there was a top gear episode where they had a British tug-of-war team pulling against some merc with 700+ hp. In SI units, a Watt is 1 Joule per 1 Second. Your scenario would be determined by many factors, especially the power curve of the motor in question. Another method to check the power of your vehicle is by checking the size of the engine and number of the cylinder it consists. If you live in the United States or Canada, those numbers will be listed with the units of SAE certified Horsepower (which is the same as horsepower, but certified by the SAE ) … SEE MORE: Horsepower VS torque- The complete difference We did a very simple and crude experiment in my high school science class years ago. You must log in or register to reply here. He developed his steam engine to perform work, which is measured as torque. Worker A has less torque (can only carry 50 pounds) but can load faster, so that figures out to more horsepower. This device measures torque and uses Watt’s equation to convert to horsepower. Click on "Torque", enter the horsepower and rpm, click on "Calculate" and the answer is 336.13 foot pounds. You might naturally and understandably reply, 'one you fool', but think about it for a minute. Click on "Horsepower", enter the torque and rpm, click on "Calculate" and the answer is 361.77 horsepower. The term horsepower was invented by James Watt, who made significant improvements to the steam engine. So choose either of the methods to calculate the average horsepower of a car. Futures: at least 10 minute delayed. Understanding and maintaining wastegate devices on engines, Farmer Tested and Farmer Approved UTVs in 2020, New sizes of winter tires for compact tractors. Eventually, Watt figured out a mathematical way to assign a value for the amount of horses an engine would substitute. Based on readings from a torque sensor developed by AVL Racing, the US Army Top Fuel dragster recorded a peak 11,051 horsepower during a recent test in California.. That surpasses even the most optimistic of estimates that the drag racing industry has tossed around for the past quarter century. Crossposted by. If that same engine is modified to maintain 650 ft.-lbs. When Watt made his improvements to the steam engine, he understandably wanted to convince people to buy it. If this is actually 10 times the power of a horse then a vespa weighed down to 400kg (my guess at the weight of a horse) should not only be able to move itself at considerable speed, but should also be able to beat up to 9 horses in a tug-of-war. The top gear top tip was something like "If you want a car with the most horsepower, buy 10 big burly blokes instead". If you made some special pulleys/gears and you are not losing much power on friction, then 10hp motor will … If two entities are locked and pulling in opposite directions, the one that "wins" will be able to generate the most effective force in the opposite direction. When purchasing a new car, the crib sheet includes two output numbers with the engine: horsepower and torque.
