Can somebody give me a short defination of youngs modulus?
I think its the way a material acts under pressure, is this correct?

Young's Modulus, also known as the modulus of elasticity, is a measure of the stiffness of a material. It represents the amount of stress a material can withstand before it starts to deform or change shape.
To calculate Young's Modulus, you divide the stress applied to a material by the strain caused by that stress. This is represented by the equation E = σ/ε, where E is Young's Modulus, σ is stress, and ε is strain.
Young's Modulus is typically measured in Pascals (Pa) or Megapascals (MPa). However, it can also be expressed in other units such as pounds per square inch (psi) or kilograms per square millimeter (kg/mm²).
Young's Modulus varies greatly between different materials. For example, rubber has a very low Young's Modulus, meaning it is very elastic and can be stretched easily. On the other hand, steel has a high Young's Modulus, making it more difficult to deform.
Young's Modulus is an important property in materials science because it helps engineers and scientists understand how a material will behave under stress. It is also used to determine the strength and stiffness of different materials, which is crucial in designing structures and products for various applications.
