which would have been described in unit of time if the angular velocity at the
instant in question were maintained constant for so long . In this respect the TT

The unit angular velocity is that of a point which describes , or would describe ,
unit angle about a fixed point in unit of time . The usual unit angle is ( as
explained in treatises on plane trigonometry ) that which subtends at the centre of
a circle ...

... its numerical measure greater than unity . In the diagram of $ 152 , the ratio of
DB to EB , or of EA to DA , is the ratio of the shear . 154. The amount of a shear is
the amount of relative motion per unit distance between planes of no distortion .

Then M = Vp ; if we so take our units that unit of mass is that of unit volume of a
body of unit density . If the density be not uniform , the equation M = Vp gives the
Average ( $ 26 ) density ; or , as it is usually called , the Mean density , of the
body ...
