When a load is placed on a truck with a C-channel,ladder frame,which ONE of the following is true of the C-channel rails?

A) neutral fiber is under compressional force
B) upper flange is under tensional force
C) lower flange is under tensional force
D) the entire rail is under compressional force

C-Channel

A structural beam with a C-shaped cross-section, commonly made of steel, used in construction for framing and supports due to its strength and simplicity.

Neutral Fiber

Neutral fiber refers to an imaginary line within a beam or other structural element under flexure where the fibers (material) are at neither compression nor tension.

Tensional Force

The pulling force applied to an object that can cause it to stretch.
