2. Depth of neutral axis increases
3. Lever arm increases
4. Lever arm decreases

Answer: B. Depth of neutral axis increases

## As the percentage of steel increases, depth of neutral axis increases.

Solution

As the percentage of steel increases, the depth of the neutral axis increases. A balanced section will have a larger carrying capacity for tensile stress if the area of steel is increased. The neutral axis must descend in order to counteract or generate equivalent compressive stress or force.

In a rectangular beam segment that is singly reinforced,

xu/0.87fyAst/0.36fckbd

Implies that , xu ∝ Ast

Which means as the percentage of steel increases, depth of the neutral axis also increases.
