Drawbridges, such as this one at the Tower of London, are raised and lowered by cable systems. 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 = 85 o as measured relative to the black hinge axis, the tension (magnitude) in each cable is T = 500 N and the relevant dimensions are a = 360 cm, b = 100 cm, c = 520 cm and d = 390 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.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
