Average full-size passenger cars have a drag area of roughly 8 sq ft (0.74 m 2). Reported drag areas range from the 1999 Honda Insight at 5.1 sq ft (0.47 m 2) to the 2003 Hummer H2 at 26.5 sq ft (2.46 m 2). The drag area of a bicycle (and rider) is also in the range of 6.5–7.5 sq ft (0.60–0.70 m 2). [5]
MV: Muzzle velocity, in feet-per-second; ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters ...
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy (E t) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f) for non-SI units of measure.
The Klimov VK-1 was the first Soviet jet engine to see significant production. It was developed by Vladimir Yakovlevich Klimov [] and first produced by the GAZ 116 works. . Derived from the Rolls-Royce Nene, the engine was also built under licence in China as the Wopen
It featured increased power output of 550 PS (405 kW; 542 hp) at 6,400 rpm and 628 N⋅m (463 lb⋅ft) of torque from 3,200 to 5,200 rpm. This was achieved by resin intake manifolds reducing air resistance, an enlarged duct for the intercooler, a new exhaust lowering back-pressure and sodium-filled exhaust valves reducing the temperature of the ...
The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.
The Hyundai Beta engines are 1.6 L to 2.0 L I4 built in Ulsan, South Korea.. All Beta engines are dual overhead camshaft valvetrain design.The Beta engine uses a direct-acting overhead cam valvetrain arrangement which places the camshaft in the cylinder head above the pistons and combustion chamber and operates the valve tappets/lifters directly.
In aircraft particularly, vertical g-forces are often positive (force blood towards the feet and away from the head); this causes problems with the eyes and brain in particular. As positive vertical g-force is progressively increased (such as in a centrifuge) the following symptoms may be experienced: [citation needed]
