A fast-paced drill on where beams are most and least stressed, in the style of the Zetamac arithmetic game. Each problem shows a beam with numbered points. Press the number of the right point, or click it. A wrong answer costs you one second.
Bending stress is taken as σ = −My/I and shear stress as τ = VQ/Ib on a solid rectangular section. Self-weight is ignored.
Pick at least one question and one beam.
