Answer to Problem 26CT
Solution:
The cable must be able to endure a tension of approximately
Explanation of Solution
Given information:
A
Explanation:
Draw a force diagram by using the force
The tensions in the cable are the magnitudes
The magnitude of the force vector
Here
Using the right angle triangle in the sketch it is observed that,
Now write each force vector in terms of the unit vectors
Here,
Hence, the force vectors
Here,
Hence, the force vectors
The angle between vector
Hence, the force vectors
Since the system is in equilibrium,
By comparing components,
By solving
Consider
Substitute
Therefore, the cable must be able to endure a tension of approximately
