Question

The proposition that a compressive load should be located within the middle third of a horizontal section of a column or wall to prevent tensile stresses from developing in the section.

A) Kern area principle
B) Euler's formula
C) Slenderness ratio
D) Neutral axis concept

Answer 1

The correct answer to the proposition about compressive loads and tensile stresses is the Kern area principle. This principle ensures structural stability under compressive loads without tensile stress damage.

Step-by-step explanation:

The proposition that a compressive load should be located within the middle third of a horizontal section of a column or wall to prevent tensile stresses from developing in the section is referred to as the kern area principle.

This principle is important in structural engineering because it helps ensure that when a column or wall is subjected to a compressive load, such as the weight of a structure above, it does not develop tensile stresses that could lead to cracking or failure. The choice among the given options is A) Kern area principle.
