Beam section and shear stress.

[QUOTE="PhanthomJay, post: 4378441, member: 58874"] I guess we need your thoughts on this first as to what you think should be the value to use, T or 2T. Does the 2nd leg serve any purpose in strengthening the section in bending and shear?the area to be used in determining Q depends on the location in the cross section where you want to determine the shear stress. So in determining Q, you could use the area above or below that location to find the shear stress at that location. Q is max at the _____?____ of the cross section, but might there be a case, in general, where the shear stress is max elsewhere?Back to the first question, is it T or 2T? Supposing you just wanted an average shear stress in the vertical legs instead of the max shear stress, would you ust the area of one leg or both in your V/A calc? [/QUOTE]
