Question
Name the four strengthening techniques.
Answer
Struts and ties, shape, lamination, and composite materials. Three of the four add almost no material.
Question
Why is shape the cheapest way to stiffen something?
Answer
It uses the same material formed differently, and bending stiffness rises with the cube of depth — so a fold, a rib or a tube buys enormous stiffness for no extra material.
Question
How does lamination strengthen a material?
Answer
Thin layers are bonded with alternating grain, so the weak direction of one layer is the strong direction of the next. It also resists splitting and warping and allows curved forms.
Question
Which way does a gate brace run, and why?
Answer
From the bottom hinge corner up to the top latch corner, so it works in compression. The other way it is in tension and a timber joint pulls apart.
