On land, the speed record registered by a rider on a 200-meter flying start speed trial was 133.28 km/h (82.82 mph) by the Canadian Sam Whittingham riding the Varna Tempest, a streamliner recumbent bicycle in 2009, [19] at Battle Mountain, Nevada. His record has been surpassed by 0.5 km/h by Sebastiaan Bowier of the Netherlands in 2013 setting ...
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
On many kinds of disc recording media, the rotational speed of the medium under the read head is a standard given in rpm. Phonograph (gramophone) records, for example, typically rotate steadily at 16 + 2 ⁄ 3, 33 + 1 ⁄ 3, 45 rpm or 78 rpm (0.28, 0.55, 0.75, or 1.3, respectively, in Hz). Air turbine rotating up to 1 500 000 rpm (25 kHz)
85 – the load index, a maximum of 515 kg (1,135 lb) per tire in this case; H – the speed index, this means the maximum permitted speed, here 210 km/h (130 mph) The tires on a Hummer H1 might be labeled: 37X12.5R17LT. 37 – the tire is 37 in (940 mm) in diameter; 12.5 – the tire has a cross section of 12.5 in (320 mm)
Tangential speed is the speed of an object undergoing circular motion, i.e., moving along a circular path. [1] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Travelling a greater distance in the same time means a greater speed, and so linear speed ...
Definitions. In the broad sense, specific "rolling resistance" (for vehicles) is the force per unit vehicle weight required to move the vehicle on level ground at a constant slow speed where aerodynamic drag (air resistance) is insignificant and also where there are no traction (motor) forces or brakes applied.
Trap(s) – the 20-metre (66 ft) speed trap near the finish line to measure speed & E.T. Trap speed – the speed measured by the 60 foot speed trap near the finish line, indicating maximum speed reached in a run. Tire shake – violent shaking of the car as the tires lose and regain traction in quick succession.
Dynamometer. A chassis dynamometer. A dynamometer or "dyno" for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
