This is merely mentioned now in order to show the necessity for , and the value of
, the preliminary matter we are about to introduce . 6. Thus it appears that there
are many properties of motion , displacement , and deformation , which may be ...

That there is at every instant a definite velocity for any moving point , is evident to
all , and is matter of everyday conversation . Thus , a railway train , after starting ,
gradually increases its speed , and every one understands what is meant by ...

It is very flexible , and we can easily form the conception from it of a sheet of ideal
matter perfectly flexible . It is very inextensible ; that is to say , it yields very little to
any application of force tending to pull or stretch it in any direction , up to the ...

If , when the matter occupying any space is strained in any way , all pairs of
points of its substance which are initially at equal distances from one another in
parallel lines remain equidistant , it may be at an altered distance ; and in parallel
lines ...

From this follows the remarkable corollary that three pure strains produced one
after another , in any piece of matter , each without rotation , may be so adjusted
as to leave the Q1 PP body unstrained , but rotated through some angle ...
