In each case, the displace-ment vector, d, shown in Figure 4–2, is the same. This displacement vector is called a resultant vector. A resultant is a vector that is equal to the sum of two or more vectors. In this section, you will learn two methods of adding vectors to find the resultant vector.
Triangle Law of Vector Addition To add two vectors u and v, place the tail of the second vector at the tip of the first. The sum u v is the vector starting at the tail of the first vector and finishing at the tip of the second. Example Use the Triangle Law of Vector Addition to draw the sum (resultant) of the following pair of vectors. Example
Example. Given two vectors!v1 and!v2 with an angle of 30 between them, 3 and !v2 j j = 4, determine !v1 j +!v2 j. Solution. !v1 +!v2 . We start by using the parallelogram law to. nd. !w =!v1 +!v2 . Now we can use the triangle, formed by the parallelogram law to know !v1 j j = 3 and !v2 j j. nd the magnitude of !w j j.
Triangle Law of Vector Addition is used to add two vectors when the first vector's head is joined to the tail of the second vector and then joining the tail of the first vector to the head of the second vector to form a triangle, and hence obtain the resultant sum vector.
Add together the following vectors graphically and numerically (by component), giving the magnitude and direction of the resultant and the equilibrant.
MATHEMATICAL VECTOR ADDITION. Part One: The Basics. When combining two vectors that act at a right angle to each other, you are able to use some basic geometry to find the magnitude and direction of the resultant. What is a resultant? A resultant is the sum of the addition of two vectors.
Triangle Law of Vector Addition Let a and b be and 2 vectors arranged head to tail. The sum a + b is a vector from the tail of a to the head of b. Last day we learned about opposite vectors, what would happen if a vector b was added to its opposite vector —b?
