14. Shear stresses in beams Flashcards
1
Q
What is the equation for distribution of shear stresses due to shear force, Q in a beam?
What is the average shear stress and any assumptions?
A
2
Q
What is the equation for shear stress distribution for a rectangular beam cross section?
What is this distribution like? Where is it max and min
A
3
Q
What is the equation for maximum shear stress using shear stress coefficient?
A
4
Q
What is the equation that relates maximum normal (bending) stress to maximum shear stress?
How does shear and bending stress vary in a beam
A
Note:
* For the distribution of bending and shear stress. understand that moment depends on x, and bending stress depends on moment and y. While shear stress only depends on y and usually doesn’t depend on x.
