anonymous283 wrote:This question has me confused on the terms: width, breadth, thickness, depth between wood and steel. If a board becomes a beam then its width becomes its depth which is confusing because steel's width is what a wooden beam's depth or thickness is called when its a board right? The correct answer here is the wood's depth but are we talking about shrinkage from top to bottom of joist or side to side if looking at the joist in section? If its tangential and the wood is cut perpendicular to grain (right) then wouldn't it be side to side which is thickness?

I've seen giant spaces of polished concrete floor without a control joint. I understand control joints are needed for exterior concrete paving every 5 feet but is that the same for interior poured concrete forms?

anonymous283 wrote:I said a. I don't understand how high NRC means low STC when NRC is how much sound something can absorb = reduction in sound. I tried looking this up and no where does it say that high NRC means low STC
