39. The resultant vector is positioned. Now, to add vectorially, the vectors are solved as
sides of an equivalent right triangle. The drawings below show a vector diagram and is
equivalent right triangle.
Vector diagram.
Right triangle.
The horizontal side of the right triangle is equivalent to the x vector (the vector drawn on
the X axis).
Make a small x by the correct vector in the vector diagram above.
The vertical side of the right triangle is equivalent to the y vector (the vector drawn on the
Y axis).
Make a small y by the correct vector in the vector diagram above.
The broken line on the vector diagram is an imaginary line that represents the y vector
and is placed to indicate the vertical side of a right triangle.
Make a small (y) by the broken line on the vector diagram.
The hypotenuse of the right triangle is equivalent to the r vector (resultant vector).
Write the word, hypotenuse, by the correct side of the triangle above; then make a small r
by the correct vector in the vector diagram.
