6. A traffic light weighing 139 N hangs from a cable tied to two other cables fastened to a support as the figure. The upper cables make angles of 0 = 40.0° and Oz 60.0° with the horizontal. Find all tensions in these cables.
A traffic light of mass m=12.5kg hangs from a cable tied to two other cables fastened to a support. The upper cables make angles of 37 and 53 with the horizontal (see figure below). Find the tension in the three cables.
7:24 PM Wed Nov 20 PRACTICE IT Use the worked example above to help you solve this problem. A uniform horizontal beam 5.00 m long and weighting 2.97 x 10N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53.0 with the horizontal (Figure (a)). If a person weighing 6.09 x 10° N stands 1.60 m from the wall, find the...
PRACTICE IT Use the worked example above to help you solve this problem. A sled is tied to a tree on a frictionless, snow-covered hill, as shown in Figure (a). If the sled weighs 75.0 N, find the magnitude of the tension force T exerted by the rope on the sled and that of the normal force ni exerted by the hill on the sled.

PRACTICE IT Use the worked example above to help you solve this problem. A uniform ladder I 10.0 m long and weighing W52.9 N rests against a smooth vertical wall. If the ladder is just on the verge of slipping when it makes a 0 47.00 angle with the ground, find the coefficient of static friction between the ladder and ground. 0.536 X Your response differs from the correct answer by more than 10 %. Double check your calculations. EXERCISE...
