Dynamic modulus

Dynamic modulus is basically a measure of how squishy or stiff something is when you hit or push it. Think of it like a ball. Some balls bounce high when you throw them, while others barely bounce at all. This has to do with how squishy or stiff the ball is.

Dynamic modulus works the same way. Engineers use it to help figure out how a material will behave when it is subjected to forces like compression, tension or shear. For example, they might use it to design a bridge that needs to withstand the weight of cars and trucks driving over it.

To measure dynamic modulus, engineers use a machine that applies a force to a small piece of the material and then measures how much the material deforms, or squishes down, in response. They then use this information to calculate the dynamic modulus.

Dynamic modulus is important because it helps engineers determine whether a material is strong enough to withstand the forces it will be subjected to. A material with a high dynamic modulus will be stiff and resistant to deformation, while a material with a low dynamic modulus will be more squishy and prone to deformation.

Overall, dynamic modulus is a useful tool for engineers who need to design structures and materials that can withstand a wide range of forces and conditions.
