R = X = R = Y = 0: Question 4 Instead of buying a pull-up bar, your friend decides to build his own frame to cut costs. You figured it is best to analyse the force system before someone gets injured. For the loaded structure shown: (i) (ii) (iii) Find the resultant R and express in conventional vector notation. Find the magnitude R and the orientation of the resultant with respect to the x-axis. Determine the position X where the line-of-action of the resultant intersects the x-axis and the position Y where the line-of-action of the resultant intersects with the y-axis. 800 N 0.7 0.8 1.5 kNm 650 N All dimensions in m
