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.
