A pound-foot (lb·ft or lbf·ft) is a unit of torque (a pseudovector). One pound-foot is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point. One pound-foot is approximately newton meters. The name "pound-foot", intended to minimize confusion with the foot-pound as a unit of work, was apparently first proposed by British physicist Arthur Mason Worthington. However, the torque unit is often still referred to as the foot-pound (ft·lb or ft·lbf). ==References== de:Foot-pound l 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「Pound-foot (torque)」の詳細全文を読む スポンサード リンク
