A fresh set every day. Short, practical, and written the way it actually matters on site.
Moment of Inertia
A section's geometric resistance to bending.
On siteIt scales with depth cubed, which is why a beam laid on edge is dramatically stiffer than the same one laid flat.
Stirrups
Closed loops of steel tying the main bars and resisting shear.
On siteThey are spaced closest near supports, where shear peaks — not uniformly along the beam.
Contour Line
A line joining points of equal elevation on a plan.
On siteClosely spaced lines mean steep ground. Reading the spacing tells you the earthwork before any calculation.
Angle of Repose
The steepest natural slope loose material holds without sliding.
On siteIt governs safe excavation batter. Cutting steeper than this is how trench collapses kill people.
Liquefaction
Saturated loose sand temporarily behaving as a liquid during shaking.
On sitePore pressure spikes and the soil loses all shear strength. Foundations sink or tilt bodily.
