Chapter guides following the course outline week by week. Each one starts from the question the topic exists to answer, builds the intuition with an analogy and something you can drag, and only then does the algebra.
Why equilibrium alone sometimes isn’t enough. The counting formulas for beams, frames and trusses, equations of condition, and the cases where counting lies to you.
Hooke’s hanging chain inverted: the funicular shape that carries load in pure compression. Cable sag and tension, the three-hinged arch, and horizontal thrust.
The diagram a moving load demands. Building ILs from first principles, Müller-Breslau’s shortcut, and using them for point loads, UDLs and wheel trains.
Influence lines find the worst case at a section you choose; this finds it anywhere in the beam. The moment envelope and the resultant-bisection rule.
These follow the same course outline and are not written yet — the cards are here so you can see where the series is going.
BNBC 2020 in practice — velocity pressure, exposure and importance, the base shear, and how it gets distributed up a building.
Getting a usable answer for an indeterminate frame in minutes — the portal and cantilever methods, and knowing when each assumption is safe.
The unit-load method for beams, frames and trusses, and why a dummy load is the cleanest route to a real deflection.
