Question 1 of 10
Single answer
Why does a thin, flat strip of steel become stiff and useful as a light-gauge (cold-formed) stud?
A
Because cold-forming hardens the steel until it is as strong as hot-rolled structural steel
B
Because bending it cold into a C-section with depth and returns gives it stiffness for its weight, as folding gives a sheet of paper rigidity
C
Because the galvanising coating adds most of the structural strength
D
Because thin steel is inherently stiffer than thick steel
