It is clear that these three elementary component strains may be applied in any
other order as well as that stated . Thus , if the simple elongation is made first ,
the body thus altered must get just the same shear in planes perpendicular to the

brought together , do not touch at a point merely , but mould each other so as to

to define the centre of inertia of a system of material points , whether given equal
or not .

... be the equivalent of any number of simultaneously acting forces . Hence The
resultant of any number of forces ( applied at one point ) is to be found by the
same geometrical process as the resultant of any number of simultaneous
velocities .
