Let's say I give you a lovely red oak beam, with a modulus for elasticity of 1,820,000 psi (That's pound per square INCH). Let's say we're going to exert a force of 9000 pounds on it in the middle of the beam, with the beam's span equaling 157 in and a moment of inertia of 45.6 in^4. You now have all the information you need, tell me what the maximum deflection is going to be! (No units needed). Please round to 3 decimal places.
