How is the flow at the rear window influenced?
The flow pattern at the rear window was already shown in Figure 4. The structures are influenced by different parameters, like the slant angle of the window or the vortices from the pillars and the antenna. Distinct are the crossflow separations produced by the antenna and at the pillars, which could be seen in already in Figure 4c.
What kind of car has a stepped rear window?
A notchback car style has a stepped rear end body profile in which the passenger compartment rear window is inclined downward to meet the horizontal rearward extending boot (trunk) lid (see Fig. 14.46 ).
What was the point of the movie Rear Window?
It’s a point Rear Window does, after all, make with a bit of humor when Miss Torso’s true love is revealed to be a short, nerdy-looking soldier. Hitch’s point: people are more than one thing or what they appear to be at any given fraction of a moment of a life.
Why does rear window still speak to US?
Those impulses haven’t gone away, which is why it’s not surprising that Rear Window continues to be a potent reflection of society – all the more so since technology has further enabled us to peer in on each other’s lives. Here then are five ways – not all of them exclusively about surveillance – that Rear Window continues to speak to us today.
What should be the impact speed of a car bumper?
Five miles per hour is a benchmark, an impact speed at which bumpers could easily — but generally don’t — prevent all but very minor cosmetic damage in barrier tests.
Why did the government roll back 2.5 mph bumpers?
The principal argument used to justify the rollback of federal requirements was that 2.5 mph bumpers would weigh less — thus reduce gas consumption — and would cost $18-35 (1982 dollars) less per car. The government argued that consumers would spend more money on a car with 5 mph bumpers and on gas than they would save from lower repair bills.
What was the speed limit for bumpers in 1982?
In 1982, the federal government bowed to pressure from automakers and rolled back impact test requirements from 5 to 2.5 mph for 1983 and later model cars. The 2.5 mph standard also allows unlimited damage to the bumper and attachments.
What’s the difference between 5 mph and 10 mph bumpers?
The “5 mph” label doesn’t mean that in real, as opposed to test, crashes the bumper would prevent damage only at speeds slower than 5 mph. Institute tests show 5 mph bumpers reduce repair costs in 10 and 15 mph crashes, too.
