For the beam and loading shown, determine:

A. The maximum shearing force in the beam = kips

B. The maximum bending moment in the beam = kip in

C. The centroid of the cross section is at (in.) from the bottom b

D. The moment of inertia of the cross section = in^4

E.the shearing stress at point a = ksi

F. The shearing stress at point b = ksi

G. The max shearing stress in the cross section = ksi

H. The maximum compressive stress inthe beam = ksi

I. The maximum tensile stress in the beam = ksi

J. The normal stress at point a = MPa

I need help for parts, e, f and J.
