me in the direction AD with the velocity v, the result;ant motion will be represented by Ac, cc, cc, etc.But these distances are equal, since they are by similartriangles proportional to the equal distances Ab, bb,etc. (or Ad, dd, etc.); therefore the motion of thebody in the resultant direction is… … Also, in the triangle ABC (Fig. 9) the componentvelocities are represented by AB — u, and BC(= AD) =v; the resultant velocity is AC — V; also, BAC = a,ACB (= CAD) = /?, and CBA = 180° - BAD = 180°— y z=z 180° — (a + /?). Hence the relations in direc- 26 KINEMATICS. [35. tion and magnitude of the…
