The fact is , that there are not two curvatures , but only a curvature ( as above
defined ) of which the plane is continuously changing , or twisting , round the
tangent line . The course of such a curve is , in common language , well called '
tortuous ...

The same is true of moments of forces and of moments of momentum , as defined
in Chapter II . First , consider two component motions , AB and AC , and let AD be
their resultant ( $ 31 ) . Their half - moments round the point o are respectively ...
