Concept explainers
The sketch shows a painter’s staging in mechanical equilibrium. The person in the middle weighs 250 N, and the tensions in both ropes are 200 N. What is the weight of the staging?
Weight of staging.
Answer to Problem 45A
Weight of staging,
Explanation of Solution
Given:
The given figure is,
Staging is in mechanical equilibrium.
Formula Used:
For mechanical equilibrium, summation of all forces is zero, that is
Calculation:
Since, the staging is in mechanical equilibrium so,
Upward force = Downward force
So,
Conclusion:
Therefore, the weight of the staging is
