(c)
To calculate: The direction of the tension force in both cases.
(c)
Explanation of Solution
Given:
The weight of the flexible steel cable,
Let the tension at the lowest point,
The tension at the points of attachment,
The direction of tension is shown in the diagram below.
Conclusion:
The direction of tension force at the lowest point is along horizontal & at the point of attachment make an angle 60° with the x-direction.
