Stress Combination

[kxa]

Here is something I have been arguing with another engineer about and wanted to what others say. It is a simple question: If you have a horizontal force and vertical force acting at the same time on a beam how the stresses should be added? I am saying that the stresses should be simply superimposed (regardless of the shape) but his thoughts were that the resultant force (sq. root of sum of sq’s) should be used to calculate the max. stress. Any thoughts?

Thanks in advance.

I didn't mean to take issue with your post. In fact, I totally agree (Notice, I was in the 8th edition, as I'm at home). I was trying to clarify the issue for those who seemed to understand the OP differently than I did.

Understand. No problem. It just rolled off my wing.

i took the sqrt of the sum of squares to refer to the vector addition (not the stress combination)
