Makana Cummins in California. Longboarding is a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels.While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers.
Almost all longboard wheels are made from urethane. The performance of longboard wheels is determined by five characteristics: height, lip shape, contact patch, durometer, and hub setting. Typical longboard wheels range from 65 to 107 millimeters (2.6 to 4.2 in) in diameter. A taller wheel will have slower acceleration but a faster rolling speed.
Diesel–electric transmission is used on railways by diesel–electric locomotives and diesel–electric multiple units, as electric motors are able to supply full torque from 0 RPM. Diesel–electric systems are also used in marine transport , including submarines, and on some other land vehicles.
A longboard generally designates a longer board variant in various board sports. Longboard (skateboard) Longboard (surfing) Longboard may also refer to Long spine board, a piece of pre-hospital emergency medical equipment
The submarine could also run its diesel using a snorkel. The Quebec had three drive shafts: a 32D 900 bhp (670 kW) diesel on the centre shaft and two M-50P 700 bhp (520 kW) diesels on the outer shafts. In addition a 100 hp (75 kW) "creep" motor was coupled to the centre shaft. The boat could be run at slow speed using the centreline diesel only.
