2004年1月5日 · The distinction between a spoiler and a wing though (as you implied) is that a spoiler acts to reduce the lift of the car and a wing creates its own lift (downward) separate from what the car body is doing. NASCAR stock cars have spoilers, Indy cars have wings.

2023年3月16日 · So with no spoiler, you get significant pull (thus drag) on the rear window. Neutral spoiler (which appears to be what the cars are using) has no significant effect on lift, but cleans up a lot of drag. Attempting to eliminate lift (last image) creates more drag.

2015年4月12日 · It is important in car wing design because it helps to increase the grip or traction of the car, allowing it to maintain stability and control at high speeds. How does the shape and angle of a car wing affect downforce? The shape and angle of a car wing can greatly impact the amount of downforce it generates.

2017年6月4日 · The front spoilers block the flow going underneath the car, thus decreasing the pressure below the car, thus reducing lift (or increasing downforce). When a car has lift or downforce, it usually creates drag. Since a typical car has some lift in its basic design, by adding a spoiler to just remove this lift force, you also reduce drag.

2011年4月17日 · The splitter on an F1 car accelerates air under the floor of the car and provides downforce further back in the car, instead of where the splitter is actually located (in front of the driver). I believe that the move to high noses from about 1993 onwards is a drive to actually increase airflow under the car in order to improve downforce created ...

2011年8月7日 · Ok, so when a car turns, the tires provide the acceleration pointing toward the center of the turn. If for some reason, I put a spoiler on my car with two rectanglular pieces, one on each side that are tilted, to the left, mocking an airplane rudder, thus when the wind has contact with them...

2022年8月17日 · The more air that goes under the car, the higher the pressure under the car. This tends to lift the car, which is the opposite of what we want at high speed (i.e. downforce). Also, if the floor of the car is rough (lots of mechanical components exposed), it creates a lot of turbulence which may add aerodynamic drag.

2013年7月14日 · A spoiler on a racing car is just an inverted airfoil (and it makes a low pressure region on the bottom surface which helps push the car into the ground for better grip). As for your question about aircraft though, I don't understand what you're trying to say. Specifically, this part:

2024年9月24日 · A car passing the first sensor starts a clock running and stops the clock when it passes the second sensor. The distance of 100 m is divided electronically by the recorded time interval and if the result is more than the speed limit of 25 m/s, a camera is triggered that takes a photo of the license plate for further processing.

2006年6月29日 · OK, I'm giving away the ending, so don't say I didn't warn you...At the end, Superman lifts Luthor's new landmass into space. I did some rough hand calculations to figure out how much energy Superman had to use to lift the island into space. Judging from the scale presented in the movie, I'm...
