Force is recognized as acting in two ways : I ° so as to compel rest or to prevent
change of motion , and 2 ° so as to produce or to change motion . Dynamics ,
therefore , is divided into two parts , which are conveniently called STATICS and

Hence if a point have , at the same time , velocities represented by OA , AC , and
Co , the sides of a triangle taken in the same order , it is at rest . Hence the
resultant of velocities represented by the sides of any closed polygon whatever ...

one . to one of their number , imagine , impressed upon each in composition with
its own motion , a motion equal and opposite to the motion of that one , which will
thus be reduced to rest , while the motions of the others will remain the same ...

Hence , as ( is momentarily at rest , the motion of the circle circumscribing OBQA
is one of internal rolling on a circle of double its diameter . Hence if a circle roll
internally on another of twice its diameter any point in its circumference describes

0 Hence the line OI is instantaneously at rest , or the two rotations about OA and
OB may be compounded into one about 01. Draw Ip , Iq , parallel to OB , OA
respectively . Then , expressing in two ways the area of the parallelogram 1p0q ,
