Resultant Vector Triangle Method. The parallelogram OACB is constructed and the diagonal OC is drawn. Now expand A to C and draw BC perpendicular to OC.
According to the law of parallelogram vector addition. After rearranging the order in which the three vectors are added the resultant vector is now the hypotenuse of a right triangle. We can draw the force resultant but we don.
Now expand A to C and draw BC perpendicular to OC.
In case of the triangle method the vectors are drawn as described in the parallelogram method except in this method the vectors are placed head to tail and the resultant vector is drawn from the origin tail of the first vector to the. The head to tail method to calculate a resultant which involves lining up the head of the one vector with the tail of the other. Triangle Law of Vector Addition. After rearranging the order in which the three vectors are added the resultant vector is now the hypotenuse of a right triangle.
