翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Human-powered land vehicle ： ウィキペディア英語版 Human-powered land vehicle Human-powered land vehicles are land vehicles propelled over ground by human power. The main ways to support the weight of a human-powered land vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination of the above. The main methods of using human power to propel a land vehicle are some kind of drivetrain; pushing laterally against the ground with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage opposite to the direction of travel; or by propeller. Human-powered land vehicles can be propelled by persons riding in the vehicle or by persons walking or running and not supported by the vehicle. Many human-powered land vehicles can also be gravity-powered land vehicles, and vice versa, although some of the latter are quite awkward to use as the former. For example: street luges, gravity racers, and snow boards. ==Types of ground contact== There are four main ways to support the weight of a human-powered land vehicle and its contents: rolling contact as with wheels; sliding contact as with skates, skis, or runners; intermittent contact as with stilts; and no contact at all as with anything carried. Additionally, these four methods may be combined as in wheelbarrows. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Human-powered land vehicle」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
