Slenderness Ratio and Reversal of Stress due to Wind
Slenderness ratio is an important parameter in structural design, especially for tension members. It is defined as the ratio of the length of the member to its least radius of gyration. In other words, it represents the relative flexibility of the member.

When a tension member is subjected to a possible reversal of stress due to wind, it means that the direction of the applied force on the member can change. This can lead to buckling of the member if it is not adequately designed to resist such reversal of stress.

Effect of Reversal of Stress on Tension Members
When a tension member is subjected to a reversal of stress, the member experiences alternating compressive and tensile forces. This can cause instability and buckling of the member if its slenderness ratio is too high.

Maximum Slenderness Ratio for Tension Members
To ensure the stability and safety of a tension member subjected to reversal of stress due to wind, the slenderness ratio of the member should not exceed a certain limit. This limit is determined based on the material properties and design standards.

In this case, the correct answer is option D, which states that the slenderness ratio should not exceed 350.

Explanation of the Correct Answer
The slenderness ratio limit of 350 for tension members subjected to reversal of stress due to wind is based on industry standards and design codes. This limit ensures that the member is sufficiently rigid to resist buckling under alternating compressive and tensile forces.

When the slenderness ratio exceeds this limit, the member becomes more susceptible to buckling, which can lead to failure. Therefore, it is essential to design tension members with a slenderness ratio within the specified limit to ensure their structural integrity and safety.

By adhering to the recommended slenderness ratio limit, engineers can ensure that tension members can withstand the possible reversal of stress due to wind and remain stable and reliable throughout their service life.

Conclusion
In summary, the slenderness ratio of a tension member should not exceed 350 when it is subjected to a possible reversal of stress due to wind. This limit is necessary to prevent buckling and ensure the stability and safety of the member. Designing tension members within the specified slenderness ratio limit is crucial for maintaining their structural integrity and performance.
