Define a transverse load.
Show hintHide hint
Think of how the force orientation relates to the beam.
3Question 3.
What does Castigliano's theorem allow you to find?
- Displacements

- Both
Show hintHide hint
Consider what information you gain from analyzing energy in a structure.
4Question 4.
True or False: A roller support can exert moments on a structure.
- True
- False
Show hintHide hint
Think about how different support types interact with loads.
Question 5.
A cantilever beam of length 4 m with a load of 1000 N applied at 2 m from the fixed end. Determine the reactions and the deflection at the free end using energy methods.
Show hintHide hint
Break down the structure into sections and analyze each using equilibrium.
Question 6.
Consider a beam subjected to varying loads along its length. How would you modify the approach of Castigliano’s theorem?
Show hintHide hint
Think about how distributed loads change the energy calculation.
