ME 437 – Strength of Materials Solutions

The 2000 lbs creates a bending stress at Q that is tensile and is equal to: Where. Substituting into the bending formula, we get. The stress due to the axial load is compressive and is equal to: The total stress is: Problem #4. Location of centeroid: The area moment of inertia: The answer is: The stress at D is: note that c=1.5-0.667=0.833 ................
