13. Barbarians at the gate! We have a Castle Drawbridge of weight W and suspended length 6R. The Center of Gravity is off center as shown. Express all answers in terms of W and R... (Based on a problem from Openstax, College Physics) (a) Suppose the weight of a drawbridge is supported entirely by its hinges (F) and the opposite shore (V), so that its cables are slack (T = 0). So, what is the upward force from the opposite shore V? And what are the direction and magnitude of the force F of the hinges exert on the bridge when the cables are slack? SR What is tension T in the two cables? 37⁰ (b) The castle drawbridge (weight W) is about to be raised. The cables (T) are now taut (stretched). There is zero force from the bridge support on opposite bank (V=0). What is the magnitude and direction of the force Fthat the bridge hinges exerts on the bridge?
