Question

Difficulty: EasyTypes of Stress and Strain

A building's concrete foundation pillars, which support the heavy weight of the entire structure above them, are primarily subjected to tension stress.

Answer: Answer

Answer

False
The statement is false because foundation pillars are pushed down upon by the immense weight of the building they support. This squeezing action produces compression stress. Tension stress only occurs when a material is being pulled or stretched.

Step-by-Step Solution

1
Analyze the forces acting on the foundation pillars.
The pillars support the weight of the building pushing down on them from above.
Identifying the direction and nature of the force is necessary to determine the specific type of stress.
2
Determine the type of stress caused by this specific force.
The downward force of the building squeezes the pillars against the ground. This squeezing action is defined as compression.
Tension is a pulling force that stretches a material, while compression is a pushing force that squeezes or compacts it.
