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?

In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
a) What is the mechanical advantage of a wheelbarrow, such as the one in Figure 9.24, if the center of gravity of the wheelbarrow and its load has a perpendicular lever arm of 5.50 cm, while the hands have a perpendicular lever arm of 1.02 m? (b) What upward force should you exert to support the wheelbarrow and its load if their combined mass is 55.0 kg? (c) What force does the wheel exert on the ground? Figure 9.24 (a) In the case of the wheelbarrow, the output force or load is between the pivot and the input force. The pivot IS the wheel's axle. Here, the output force is greater than the input force. Thus, a wheelbarrow enables you to lift much heavier loads than you could with your body alone. (b) In the case of the shovel, the input force is between the pivot and the load, but the input lever arm is shorter than the output lever arm. The pivot is at the handle held by the right hand. Here, the output force (supporting the shovel's load) is less than the input force (from the hand nearest the load), because the Input is exerted closer to the pivot than is the output
Explain the need for tall towers on a suspension bridge to ensure stable equilibrium.
When visiting some countries, you may see a person balancing a load on the head. Explain why the center of mass of the load needs to be directly above the person's neck vertebrae.

Suppose a 900-kg car is on the bridge in Figure 9.34 with its center of mass halfway between the hinges and the cable attachments. (The bridge is supported by the cables and hinges only.) (a) Find the force in the cables. (b) Find the direction and magnitude of the force exerted by the hinges on the bridge.
The center of gravity of an ax is on the centerline of the handle, close to the head. Assume you saw across the handle through the center of gravity and weigh the two parts. What will you discover?

A 20.0m -tall hollow aluminium flagpole is equivalent in strength to a solid cylinder 4.00cm in diameter. A strong wind bends the pole as much as a horizontal 900.0N force on the top would do. How far to the side does the top of the pole flex?
