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 wooden door 2.1 m high and 0.90 m wide is hung by two hinges 1.8 m apart. The lower hinge is 15 cm above the bottom of the door. The center of mass of the door is at its geometric center, and the weight of the door is 260 N, which is supported equally by both hinges. Find the horizontal force exerted by each hinge on the door.
In Example 14.3, we found that one of the steel cables supporting an airplane at the Udvar-Hazy Center was under a tension of 9.30 103 N. Assume the cable has a diameter of 2.30 era and an initial length of 8.00 m before the plane is suspended on the cable. How much longer is the cable when the plane is suspended on it?
A uniform horizontal strut weighs 400.0 N. One end of the strut is attached to a hinged support the wall and the other end of the strut is attached to a sign that weighs 200.0 N The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the s find the tension in the cable and the force at the hinge of the strut.
A 3.0kg uniform pole 1.8m long is held horizontal by a hinge to a wall and supported by a cable attached to its center which forms a 45° angle with the pole. A large bird house with a mass of 6.6kg is at the end of tge pole. Find the force that the hinge exerts on the pole.

Item 2 Consider the crane system in (Figure 1). It can be operated so that the steel beam ratates around the orange axle. The crane is supported by a steel cable attached to it 6.0 mm from the upper and making a 30 angle. The steel beam is 32 1n in length and weighs 25,000 N. The beam's unique design causes the center at gravity to be at a point 12 m along the beam from the ground.
