The French know this, allowing their autoroutists to do 130kph (81mph) inbonnes conditions. Yet Brits apparently can’t be trusted beyond 70, and no politician will ever change this, because apparently suggesting a modest increase in motorway speeds is the moral equivalent of campaigning...
When the airspeed reached about 17 mph (27 kph), I could feel the hang glider lift me off the ground. As I was lifted, I moved my hands from the sides of the control bar to either side of its base. To fly, I had to do two things: maintain a constant speed and keep my ...
and this drogue is out during the entire free fall. Without this drogue, the combined weight of the instructor and student would cause the pair to fall at 180 to 200 mph (290 to 320 kph) -- much faster than the normal 120 mph. The drogue slows the pair down to...
The fuel load is 800 to 1,000 pounds (about 450 kg) of fuel at launch, or approximately 150 gallons (600 liters). The missile has a cruising speed of 550 mph (880 kph). Guidance Tomahawk cruise missile escorted by F-14 Photo courtesy U.S. Navy The hallmark of a cruise missile...
(approx. 4-foot/1.2-m diameter) drogue chute, and this drogue is out during the entire free fall. Without this drogue, the combined weight of the instructor and student would cause the pair to fall at 180 to 200 mph (290 to 320 kph) -- much faster than the normal 120 mph. The ...
Bubilek quotes the total weight at 150 pounds (70 kilograms), compared to about 500 pounds (225 kilograms) for a typical sports bike, and the top speed at 70 mph (112 kph) [source: Sport Rider]. That's comparable to the average all-gas-powered scooter and a lot faster than the ...
Carried aloft atop a Languedoc 161 airliner, it flew for 12 minutes and reached 450 mph (724 kph) at half power [sources: Siddiqi; Ward; Wolko; Yust et al.]. And, for a while, that was that. Despite Leduc's success, lack of funds ended official support for his research in 1957 [...
A typical Perseid meteoroid (which is what they're called while in space) moves at 133,200 mph (214,365 kph) when it hitsEarth's atmosphere(and then it is called a meteor). Most of the Perseids are tiny, about the size of a sand grain. Almost none of the fragments hit the ground...
Suspension design is all about compromise. For optimal handling, a car ideally needs to be quite firm, avoiding body roll and pitch and maintaining a good tyre contact patch with the road. But a stiff setup also makes a vehicle ride harshly on the road. Soften the damping too much and yo...
93. EV Mode:applying to both hybrids and plug-in hybrids,EVMode stands for zero-emission driving. The 2024 model year Chevrolet Corvette E-Ray, for example, has something called Stealth Mode for quiet driving at speeds up to 45 mph (72 kph). ...
