Lesson 20

Beam Deflections III

Learning outcomes

    1. Explain whether a portion of a beam is curved or straight by referring to the moment diagram.
    2. Use superposition to combine tabulated values of v and θ to solve unknown deflections and slopes for determinate beams.
    3. Apply small angle theory to determine deflection of a straight segment when a slope and length are known.
    4. Evaluate the elastic curve equation v(x) for any value of x in order to compute v.
    5. Use superposition to compute deflection and slope for a simply-supported beam with a loaded overhang.
    6. Use combinations of positive and negative distributed loads as necessary for superposition.
