A cargo ship has been badly loaded and is dangerously down at the stern. Fortunately, there is a massless crane based on the ship near its bow. The captain decides to balance the ship by using the crane to lift a container from near the stern, move it horizontally forwards, and lower it onto the bow. When does the ship's angle begin to improve?

Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle? FIGURE P5.76
Two telephone poles are separated by 40 m and connected by a wire. A bird of mass 0.5 kg lands on the wire midway between the poles, causing the wire to sag 2 m below horizontal. Assuming the wire has negligible mass, what is the tension in the wire?
A picture frame hung against a wall is suspended by two wires attached to its upper corners. If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0.75 of the weight of the frame?
A delivery truck is carrying a 120 kg refrigerator. The refrigerator is 2.20 m tall and 85.0 cm wide. The refrigerator is facing sideways and is prevented from sliding. The center of gravity of the refrigerator is located at its geometrical center. Determine the maximum acceleration that the truck can have before the refrigerator begins to tip over.
The distance between two telephone poles is d = 54.0 m. When a 1.20 kg bird lands on the telephone wire midway between the poles, the wire sags h = 0.206 m. How much tension (in N) does the bird produce in the wire? Ignore the weight of the wire
A painter with 80 weight is on a 4 meters long platform. Platform has negligible weight. The painter is balanced by two cables. One is at the left end and the other one is 3.2 meters away from the first cable. a)What is the tension on the left cable and the right cable when the painter is in the middle of the platform b)Would the painter be able to move the right end of the platform without loosing balance. Calculate the tensions on the cables for that case and show that it leads to a negative tension.
Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the surface of the door. One child pushes with a force of 17 N at a distance of 0.585 m from the hinges, and the second child pushes at a distance of 0.465 m. What is the magnitude of the force, in newtons, the second child must exert to keep the door from moving? Assume friction is negligible. F2=
.A monkey is hanging on a tree branch that is inclined upwards 30 degrees from the horizontal to grab a hand of bananas. He is about 4 m from the tree trunk and the bananas are still 3 meters away from its position. Use the principle of static equilibrium to determine the mass of the monkey if the mass of the bananas is 5 kg.
The figure below shows a bird feeder that weighs 177.7 N. The feeder is supported by a vertical wire, which is in turn tied to two wires, each of which is attached to a horizontal support. The left wire makes a 60° angle with the support, while the right wire makes a 30° angle. What is the tension in each wire (in N)? left wire= ? N right wire= ?N bottom wire= ?N
Equilibrium: The mobile shown in the figure is perfectly balanced, and the horizontal supports have insignificant masses. What must be the masses of the suspended objects m 1, m 2, and m 3 to maintain balance? m 1, m 2, m 3=
4. You have been tasked with retrieving a crate from a 4-m long beam that is suspended by two cables, as shown. While standing 1.5 m from the left edge of the beam, you silently hope that the cables are strong enough to hold the weight of the beam, the box, and you! The masses of the beam and you are 10 kg and 70 kg, respectively. The cables are rated for a tension of 1000 N. Do the cables hold? In other words, what is the tension in each cable? Hint: you can assume the box is sitting on the very end of the beam. 30° 20° 4.0 m
