Help with this template Comments: edit – history – watch – refresh The formula is correct for transverse sheer stress although I think the explanation is incorrect. "I" represents the moment of inertia of the entire cross-section. "Q" is A*Y, where A is the cross-sectional area measured from the plane you want to calculate TVS to the surface, Y is the centroid of this cross sectional area measured from the neutral axis. V is the load, and T is the thickness of the cross section.

Shouldn't this be connected to faults and earthquakes? Wetman 20:35, 1 Sep 2004 (UTC)

what is Q? Richard Giuly 02:43, 27 January 2007 (UTC)

Q should be the static momentum

What static momentum? The whole equation seems plain wrong. In the area of engineering I deal with, shear stress is equal to shear force over shear area. Any reference to the bending inertia, 'I', is only relevant to longitudinal shear, not transverse shear. -- Kvetner 13:26, 9 March 2007 (UTC)

From my point of view this equation is wrong (not only this, but dimmensions are wrong). It seems to be the expression for the torsion, Kvetner, you're right, for shear stress over a beam, only moment and area matters. Somebody correct this or I'll do it myself when I learn how to edit pages. thx —Preceding unsigned comment added by Trufetes (talk • contribs) 17:33, 14 December 2007 (UTC)

the equation there is for sheer stress in a plane if that's any help
