Now consider the drawbridge illustrated below wherein the nearly horizontal brown door is centered along the vertical brick wall, the door-wall angle is α = 80 o as measured relative to the black hinge axis, the tension (magnitude) in each cable is t = 800 n and the relevant dimensions are a = 330 cm, b = 170 cm, c = 570 cm and d = 320 cm. determine the resultant torque (magnitude) | ( m r ) a x i s | in nm that the two cables contribute to the moment about the hinge axis.
