# Axes-of-rotation sentence example

Application to a Pair of TurnIng Fseces.Let ai, a2 be the angular velocities of a pair of turning pieces; Of, Oi the angles which their line of connection makes with their respective planes of rotation; Ti, r2 the common perpendiculars let fall from the line of connection upon the respective

**axes of rotation**of the pieces.The

**axes of rotation**of a pair of turning pieces connected by a link are almost always parallel, and perpendicular to the line of connection n which case the angular velocity ratio at any instant is the recipocal of the ratio of the common perpendiculars let fall from the me of connection upon the respective**axes of rotation**.The flexibility and elasticity of the kite formed by the natural wing are rendered necessary by the fact that the wing, as already stated, is practically hinged at its root and along its anterior margin, an arrangement which necessitates its several parts travelling at different degrees of speed, in proportion as they are removed from the

**axes of rotation**.The fourteen-month term is an immediate result of the fact that the

**axes of rotation**and figure of the earth do not strictly coincide, but make with each other a small angle of which the mean value is about o 15".Advertisement
