Deflection
- Span to the fourth, which is why spans are short
- One support too many, and what it costs to know
- Stiffness is not strength, and usually it is the one that governs
- The theorem that swaps the question round
- One deflection, without solving everything
- The support that moved
- The water that will not run off
Structures
- Depth is the cheapest strength there is
- The triangle that cannot fold, and everything built out of it
- The shape that carries itself, and the arch that is its reflection
- The polygon that finds the shape
- The hinge put in on purpose
- The frame that leans, and what stops it
- The line that must stay inside
- The joint that is not a pin
Internal forces
- Where to put the supports, which is not at the ends
- The diagram is an integral, and that is why it can be drawn by eye
- What a cut reveals, and why it was there all along
- After the first yield, which is not the end
- The moment over the support, and what it buys
- The worst place to stand
- The moment that will not lie flat
- The train that is worse than its heaviest axle
Equilibrium
- Counting the unknowns, and finding out whether statics can answer
- Everything adds to nothing, and that is the whole of statics
- The free body is a choice, and choosing it well is the whole skill
- Three forces must meet at a point, and a drawing can find it
- The load that is spread out, and the force that replaces it
- Answering one question without solving the rest
- The equation that is not new, and the three that are
- The count that does not see it
Sections
- The material far from the middle does nearly all the work
- The same steel in a different shape, and a factor of forty
- Plane sections stay plane, and what the assumption costs
- The shear nobody draws
- The point that is not in the section
- Bending is a pair of forces, pushing and pulling
- When half the section has given up
- The section made of pieces
