Resultant Vector By Graphical Method. The magnitude and direction of R are then determined with a ruler and protractor respectively. Calculate the magnitude of the resultant vector R using the selected scale and measure its direction with a protractor.
The graphical method of adding vectors A and B involves drawing vectors on a graph and adding them using the head-to-tail method. 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. Calculate the magnitude of the resultant vector R using the selected scale and measure its direction with a protractor.
Therefore we could add the vectors in any order as illustrated in Figure and we will still get the same solution.
Draw the resultant vector R R The resultant vector is the vector from the tail of the first vector we drew directly to the head of the last vector we drew. This method of adding vectors graphically is also referred to as the head-to-tail method analytical method and geometric method. Resultant force Vector diagrams of forces. This video focuses on how to get the resultant vector using Graphical Method.
