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.

9. an object is moved from the outdoors, which is at a temperature of 100 ºf, to a room at a temperature of 70 º f. what happens to the object when it’s placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
