A L-shaped bracket lying in a horizontal plane supports a load P as shown. The bracket has a hollow rectangular cross section. The centerline lengths of the arms are b1 and b2. Calculate the maximum tensile stress Delta t, maximum compresive stress Delta c, and maximum shear stress Tau max at point A, which is the mid point on top of the bracket at the support. P = 610 N, b1 = 440 mm, b2 = 670 mm, Theta = 30 degree.
