How Things Are Built
Ten questions on the principles engineers actually rely on, each explained by the force it manages.
About this topic
Engineering is a small set of ideas about force applied over and over at every scale, from a door handle to a suspension bridge. This quiz covers the simple machines, the geometry that makes structures rigid, the properties that decide which material goes where, and the standardisation that made mass manufacturing possible. It leaves the famous inventors to Inventions That Changed Everything and concentrates on the principles instead. The explanations name the force being managed in each case.
