Homework Help: Shear Stress

  1. Feb 14, 2010 #1

    An inclined member is braced with a glued block, as shown. The ultimate shear stress in the glued joint is 1050 psi. Determine the dimension X at which the glued joint will fail.


    I know that


    -shearstress= (Pressure x length) dived by (Area x modulus of elasticity)


    - At point A there is X forces and Y forces, at point B there is Normal Force.


    -Pressure max = (Shearstress X Area)


    ------------

    so far i know that Force at A in the X direction is 1050x (2x2) = 4200 lbs



    other than that im stuck and i dont know where to start.....any help would be appreciated.
