Definition

A type of stress that is applied to a material, especially in construction, to improve its performance and strength before it is subjected to external loads.

Example

The engineers used prestress in the concrete beams to enhance their durability.

Conversation

I just learned about the concept of prestress in my engineering class.

Oh really? What does that mean exactly?

It refers to the stresses introduced in a material to improve its performance.

That sounds interesting! I can see how it would be useful in construction.

Did you know they prestress the beams in that new building downtown?

Really? I’ve heard that helps with stability.

Yeah, it’s interesting how they apply tension to make them stronger.

Root Explanation

Prestress → It is formed from "pre-" (meaning before) and "stress" (from Latin "stringere", meaning to draw tight). The word "prestress" refers to applying a force to a material before it is subjected to additional loads, effectively drawing it tight beforehand.

Memory Tip

Think of applying a force 'before' ('pre-') putting additional weight on something, which is what prestressing does.
