Resultant Vector Using Triangle Method. A 100 Unit 40 NW B 300 Unit 80 NE 3. Substitute the value of P and Q in the formula R 3 2 4 2 2 x 3 x 4 x cos30 R 9 16 20.
To find Resultant force vector using parallelogram law of forces. Using a scaled diagram the head-to-tail method is employed to determine the vector sum or resultant. The magnitudes of the vector components A x and A y can be related to the resultant vector A and the angle th with trigonometric identities.
Now expand A to C and draw BC perpendicular to OC.
R P Q. Substitute the value of P and Q in the formula R 3 2 4 2 2 x 3 x 4 x cos30 R 9 16 20. Using Parallelogram Method Determine The Resultant Of Vectors. Triangle Method of Vector Addition This method is also known as the head to tail method of vector addition.
