Question 3 - Three forces, Fl = 56 N, F2 = 65 N and F3 = 52 N are acting on a 2.0-m-Iong uniform beam as shown in the figure. (a) Calculate the torque due each of these forces about the point C. For each force indicate whether the torque is positive or negative. {b} Calculate the torque due each of these forces about the point P. For each force indicate whether the torque is positive or negative. F1 = 56H
