Deriving the equation for Shear Stress for Different cross-sections

  1. Jul 16, 2012 #1
    Hi I know the general equation for shear stress in beams is this:
    Shear Stress τ = F/Ib ∫y dA

    Depending on the shape of the cross section (ie. If its an I beam, T-beam, hollow square/circle) , after integration we will end up with a different equation. I want to know the exact procedure to do the integration for specific cross sections.
    I want to know the derivations for the following cross sections: I-beam, T-beam, rectangular, hollow rectangular,circular and hollow circular).

    I really need some help with this because I dont understand this derivation at all
    Thank you so much!
