ollowing rule forsubtracting one vector from an-other. In order to subtract one vectorfrom another reverse the one to besubtracted and add it to the othervector. It is evident from Fig. 7 thatthe sum and the difference of two vectors form the diagonalsof the parallelogram determined by them.… … ANALYTICAL MECHANICS c2 = o2 -f- b2 + 2 ab cos 0 = (10cm.)2+(10cm.)2+2xl0cm.Xl0cm.cos(60°) = 300 cm.2c = 10 \/3 cm. = 17.3 cm.*6 sin0 tan0 a-\-b cos </> 10 cm. sin (60°)10 cm. + 10 cm. cos (60°)= |V3.0 = 30°. , « Therefore the resultant displacement is about 17.3 cm. along the direction N.…
