INTRODUCTION: 
Random loads on a truss structure are generated by the program, and you are asked to estimate the reactions that would be generated at the supports. This tests your knowledge of the principles of vector addition and the summation of forces around a point. You can choose an error tolerance for your estimates, but keep in mind that you get more points for a correct answer within a lower tolerance. Try and get to 100 points with as few tries as possible.
