simply supported timber beam is 14 feet long with cross-sectional dimensions of 4 in. wide by 10 in. tall. The beam is supported at its ends and carries a concentrated load of 5 kips at its center. The modulus of elasticity is 1.7×106 psi.

The deflection at the center is most nearly

For a simply supported beam of length L and uniform cross-section (constant E and I with usual notation) with a concentrated load P perpendicular to the beam at mid span, use first principles and method of integration discussed to obtain an expression for the maximum deflection. If the concentrated load is still perpendicular to the beam but not at the mid span, very clearly and briefly explain how you would determine the maximum deflection of the beam.
