Drawbridges, such as this one at the Tower of London, are raised and lowered by cable systems..

llustrated below wherein the nearly horizontal brown door is centered along the vertical brick wall, the door-wall angle is ?=85o?=85o as measured relative to the black hinge axis, the tension (magnitude) in each cable is T=800T=800 N and the relevant dimensions are a=a= 390 cm, b=160b=160 cm, c=560c=560 cm and d=350d=350cm. Determine the resultant torque (magnitude) |(MR)axis||(MR)axis| in Nm that the two cables contribute to the moment about the hinge axis. Please refer to attachment
