LESSON 1.4 · 2:56 · CHAPTER 1 · WHY WINDING
What we wind today
Every wound part answers one question: which way does the load go? Pipes under pressure, tanks, drive shafts, rotor sleeves and lattices each have a dominant load, and the winding angle follows it.
Predict · at 0:55 in the video
Now a pipe hanging down a deep well. It barely feels pressure; mostly it carries its own weight. Hoops, 55 degrees, or a low-angle helical?
A low-angle helical. The load runs along the pipe, so the fibre should too. Add hoops if it is pressurised as well.

About the numbers
Simulations in this lesson are our own. Where a number rests on an assumption, the video marks it with an asterisk and says where it comes from.
