The final shock wave, when it comes, is weaker and less drastic in its effect of blasting the boundary layer behind it. Such blasting causes high drag and may be disruptive enough to lead to gross loss of lift. Effects of this kind, coupled with loss of stability and control, once led...
thereby causing the fluid to move further with the surface behind the body resulting in narrower wake and considerably reduced pressure drag. Thus, the drag force is much smaller for rough-surfaced sphere or cylinder in a particular Reynolds number range compared to a smooth body of identical si...
This means that in a race situation, W’ can recover after an initial drop. By hiding in the peloton and drafting behind other riders, your W’ can accumulate sufficiently to mount a blistering attack, of precisely known power and duration. The chart above, generated inGolden Cheetah, shows ...
The diagram represents a ball that is struck or pitched in a way that propels it forward and rotates it clockwise. The wheat field pattern of arrows represents the drag force exerted by the incoming wind. The drag force is the resistance offered by the wind, the same resistance you feel w...
point-to-point and even a few licensed tracks to challenge players’ skills behind the wheel. Road Atlanta, Silverstone, Laguna Seca, Tsukuba, Road America and Nürburgring Nordschleife were the licensed courses offered alongside quite a few original tracks inspired by real-world roads and challenges...
be. Behind the glass is nothing now but empty space. No door, no window, no vent, no way through or round but to feel the rain of a thousand shards fall to the ground. I try not to howl or jump when I am cut, for cuts heal. And love lives like this: patching ...
they will be long forgotten. One way of checking your own forecasts is to take a look at the odds offered on the betting markets. These are interesting, because they reflect the actions of people who have actually put money behind their views. In an efficient and liquid market, the latest...
Photo: Top: Friction drag: The aerodynamic shape of this car allows the airflow around it to remain reasonably laminar. There is drag, but mainly caused by friction between the layers of air moving past one another at different speeds. Notice how the air becomes more turbulent behind the car...
Most important, however, is when it won’t operate: Super Cruise will disable the system for the entire drive if the driver looks away for too long, a road is unmapped, the vehicle’s data connection goes dark, or any number of failure points to keep the person behind the wheel engaged...
Suddenly, from behind the rim of the moon, in long, slow-motion moments of immense majesty, there emerges a sparkling blue and white jewel, a light, delicate sky-blue sphere laced with slowly swirling veils of white, rising gradually like a small pearl in a thick sea of black mystery. ...
