What is stifness?

Stiffness refers to the resistance of a material to deformation or bending. It is also known as rigidity or inflexibility. Stiffness is a property of a material that determines how much it will deform under a specific load or force.

Stiffness is related to the Young's modulus of a material, which is a measure of its elastic properties. The higher the Young's modulus, the stiffer the material.

Stiffness is an important factor in design and engineering. Materials with high stiffness are used in applications where rigidity is essential, such as in the construction of buildings or bridges. Conversely, materials with low stiffness are used where flexibility is required, such as in clothing or textiles.

Stiffness can also be influenced by temperature, moisture, and other environmental factors. Changes in stiffness can affect the performance and durability of a material or structure.
