the tension Ti PRACTICE IT Use the worked example above to help you solve this problem. A traffic light weighing 1.15 X 10N hangs from a vertical cable tied to two other cables that are fastened to a support, as shown in Figure (a). The upper cables make angles of 8, = 38,0° and e2 = 52.0° with the horizontal. Find the tension in each of the three cables. Ti = T₂ = T3 EXERCISE HINTS: GETTING STARTED I'M STUCK!...

PRACTICE IT Use the worked example above to help you solve this problem. In a car lift used in a service station, compressed air exerts a force on a small piston of circular cross section having a radius of r = 4.55 cm. This pressure is transmitted by an incompressible liquid to a second piston of radius 13.7 cm. (a) What force must the compressed air exert on the small piston in order to lift a car weighing 13,300 N?...
