Problem of Tensile Stress?

Stress problem !! (max height, concrete...)?

• Stress problem !! (max height, concrete...)? Hello all,,, At the moment, i need some help with understanding stress. The problem that I encountered is following... http://i75.photobucket.com/albums/i... Density of this concrete building is 156 lbs/ft^3 Stress of concrete is 15,000 psi. There are 2000 people at the top each of them weight 200 lbs. The question now is, what would be the largest diameter for the holes (they are identical) that can be drilled? Any help would be appreciated, thank you. (Explaination will get you more stars)

  I think this question got posted in the wrong category. You might want to repost it, and choose the category yourself rather than letting the system choose the category for you. You may want to consider the Home and Garden category under Home Maintenance. someone browsing there is more likely to understand the principles involved.
