4. (20 pt) A wood beam AB on simple supports with span length
equal to 9 ft is subjected to a uniform load of intensity 120 lb/ft
acting along the entire length of the beam and a concentrated load
P acting at a point 3 ft from the right-hand support (see figure).
The allowable stresses in bending and shear, respectively, are 2500
psi and 150 psi.
What is the allowable P? (Note: The width and height of the cross
section are 8 and 10 inches, respectively)
