Kindly help me pleaseeee!

The wood beam supports loads of w = 400 lb/ft and P = 920 lb on span lengths of LAB = 9.0 ft, LBC = 4.5 ft, and LcD= 4.5 ft. The beam
cross section has dimensions of b1 = 1.0 in., d = 3.0 in., bɔ = 5.3 in., and d2 = 8.00 in. Determine the magnitude and location of:
(a) the maximum horizontal shear stress in the beam.
(b) the maximum tensile bending stress in the beam.
