A 5 N picture frame is supported by two strings that run from its upper corners to a nail on the wall. What is the tension on each string if each string makes an angle of 30° with the horizontal?

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

A telephone pole is supported by a guy wire which exerts a pull of 300 N on the top of the pole. If the angle between the wire the pole is 60 degrees, what is the vertical component of the pull on the pole?

A 10 m uniform rope of 100 N is supported at two ends. A person (400 N) sits 2 m from the left side. What is the tension on the right side?
