Practice Questions

Question 1

When using the Virtual Work Method for calculating deflections, what is the significance of the 'virtual system' and the 'real system'?

Question 2

For a beam with a suddenly changing cross-section, which method for calculating deflections is generally the most computationally efficient and least prone to errors from piecewise integration?

Question 3

In the context of the Double Integration Method, if the bending moment equation for a beam segment is given by $M(x) = -w \frac{x^2}{2} + R_A x$, what is the expression for the slope $\frac{dy}{dx}$ after the first integration, assuming $EI$ is constant?

Question 4

A propped cantilever beam has one fixed end and one simply supported end. When applying the Conjugate Beam Method, what are the boundary conditions for the conjugate beam at the location of the real beam's fixed end?

Question 5

Castigliano's Second Theorem is a powerful energy method for calculating deflections. Which of the following conditions must be met for Castigliano's Second Theorem to be applicable?
