## Summary:

- I cannot visualise how the wind will cancel the tesile stress due to the selfweight

A chimney has a rectangular cross-section with external dimensions 800 × 600 mm and wall thickness 150 mm. It is 5 m high. The density of the material is 2000 kg/m3. Assuming that the material is elastic, calculate the maximum uniform wind-pressure loading (N/m2) that the chimney can withstand, acting normally to one of the 800 mm wide faces, if no tensile stress is allowed to develop on the cross-section at the base

I can see that the selfweight causes compression on the base, but how does the wind helps to cancel the tensile stress.

I will really appreciate a detailed explanation because I am a bit confused.

Thank you in advance!
