The tension in the two wires supporting the traffic light shown in figure.
Answer to Problem 13P
Solution:
195.6 N and 260.8 N
Explanation of Solution
Given:
Mass of traffic light is 33 kg
Formula used:
From second law of motion, equilibrium condition is:
Weight,
Here m is mass of traffic light and g is acceleration due to gravity.
Calculation:
Using free body diagram
(vertically downwards) The hanging traffic light in the free body diagram is in equilibrium with three forces:
Conclusion:
Thus,
