Resultant Vector Given Magnitude And Direction. The magnitude and direction of the sum of two or more vectors can also be determined by use of an accurately drawn scaled vector diagram. Determine the resultant of the given vector forces by providing your answer in terms of the magnitude and direction.
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. Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector.
There are a two different ways to calculate the resultant vector.
Putting these values and representing resultant vector OC by R magnitude of the resultant is given by R 2 P Q cos th 2 Q sin th 2 P 2 Q 2 2 P Q cos th In OCD tan a O D C D P Q cos th Q sin th Resultant acts in the direction making an angle a tan 1 P Q cos th Q sin th with direction of vector P. If two vectors are represented in direction and magnitude by two adjacent sides of parallelogram then the resultant vector is given in magnitude and direction by the diagonal of the parallelogram starting from the common point of the adjacent sides. Calculate and compare the magnitude and direction of the vector u and - 6 u with u given by u 1 1 Solution to Question 5. Add the vector equations together to get the vector equation of the resultant force.
