Plot the magnitude of the resultant R of the three forces as a function of 0 for 0≤0≤360°. After you have the plot, determine the value of which makes the magnitude R of the resultant of the three loads (a) a maximum and (b) a minimum. Record the magnitude of the resultant in each case. Use values of p = 79° y = 29°, F₁-69 N, F₂=118 N, F3 = 90 N. F₂ Answers: (a) maximum R= i N when 9- i (b) minimum R = i N when 0- i
