Express v = -11i + 5j in polar coordinates. That is, find the magnitude and direction of the vector. Express the direction as
an angle measured (in degrees) counterclockwise from the positive x-direction.
Include in your response a hand-drawn representation of the vector.
Show all relevant working.
Three tension rods are bolted to a gusset plate. Determine the magnitude and direction of their resultant. Use the vector algebra and vector polygon methods. Compare the answers from the two methods to verify the
accuracy of your work. Assume F = 520 lb, F = 220 lb, and F, = 340 lb.

- READ THIS before you start doing it this is just to get you an idea on what I am expecting : When adding several vectors together, we could add the first two, solve for the resultant using the sine and cosine laws. Then add the third vector to that resultant, to get a new resultant. Then add the fourth vector to that resultant to get another new resultant. Repeating the procedure until we arrived at the final resultant. Solving this series of triangles would be very tedious and time consuming. The better way is of course by breaking each of the original vectors into components, and finding the total [N-S] component, and the total [E-W] component. Then add these two vectors tip-to-tail to get the final resultant. Since the vectors are at right angles, you would use the pythagorean theorem to determine the final length, and SOHCAHTOA to find the direction.
