2. Shaft (golf) - Wikipedia

   en.wikipedia.org/wiki/Shaft_(golf)

   The shaft is roughly .58 inch/14.7 millimeters in diameter near the grip and between 35 and 48 inches/89–115 cm in length. Shafts weigh between 45 and 150 grams depending on the material and length. Graphite shafts are woven from carbon fiber and are generally lighter in weight than steel shafts. Graphite shafts became popular among amateurs ...

3. Hybrid vehicle drivetrain - Wikipedia

   NRG Dynamix of the U.S.A. claimed its approach reduced cost by one-third compared with electric hybrids and added only 300 lbs (136 kg) to vehicle weight vs. 1,000 lbs (454 kg) for electric hybrids. The company claimed a standard pickup vehicle powered by a 2.3-litre, 4-cylinder engine achieved 14 mpg (16.8 L/100 km) in city driving.

4. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.

6. Brake-specific fuel consumption - Wikipedia

   en.wikipedia.org/wiki/Brake-specific_fuel...

   In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2.

7. Horsepower - Wikipedia

   en.wikipedia.org/wiki/Horsepower

   The average steam consumption of those engines (per output horsepower) was determined to be the evaporation of 30 pounds (14 kg) of water per hour, based on feed water at 100 °F (38 °C), and saturated steam generated at 70 psi (480 kPa). This original definition is equivalent to a boiler heat output of 33,485 Btu/h (9.813 kW).

8. Thrust-specific fuel consumption - Wikipedia

   en.wikipedia.org/wiki/Thrust-specific_fuel...

   For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...

9. Hybrid (golf) - Wikipedia

   en.wikipedia.org/wiki/Hybrid_(golf)

   A hybrid is a type of club used in the sport of golf with a design borrowing from both irons and woods while differing from both. The name "hybrid" comes from genetics to denote a mixture of two different species with desirable characteristics of both, and the term here has been generalized, combining the familiar swing mechanics of an iron with the more forgiving nature and better distance of ...
