What are mechanical properties?

Mechanical properties are how materials react when we push, pull, or twist them, like how a toy behaves when you play with it.

Imagine you have two blocks: one is made of soft playdough, and the other is made of hard plastic. If you press your hand on the playdough, it squishes easily, that’s like being soft or squishy. But if you press your hand on the plastic, it doesn’t budge much, that's like being stiff or strong. These are all types of mechanical properties.

Some materials can stretch a lot before they break, just like a rubber band. Others snap easily, like a piece of glass. If you twist a ruler, it bends, that’s called being flexible. But if you twist something too much, it might crack or break, that’s when it loses its strength.

So mechanical properties are all about how materials behave when we use them, whether they bend, break, stretch, or stay firm. Like your favorite toy, it has its own special way of reacting to you!
