Homework Help: Finding the Resultant of two tensil forces?

    Finding the Resultant of two tensile forces?

    I'm having problems finding the resultant of these two forces both analytically and graphically. I've mad a start but I'm pretty lost. Is this all correct?

    I've managed to complete this much. If someone can finish off both solutions and explain to me I would be grateful!

    Thank you,

    We don't finish off your solutions for you here at the PF -- you do the work. Now, for the graphical part of the solution, just draw the lengths of the vectors a little more carefully. If you have graph paper or Engineering paper, thaw will make it easier. Use a protractor to get the 60 degree angle right, and use vector addition (think nose-to-tail) to add the two vectors graphically. Compare the answers you get with the two methods -- are they about the same?
