## FAQs on Young's Modulus, SOM - Topper Handwritten Notes & Videos for GATE ME - Mechanical Engineering

 1. What is Young's Modulus?
Young's Modulus, also known as the modulus of elasticity, is a measure of the stiffness of a material. It quantifies how much a material deforms under a given amount of stress. It is denoted by the symbol "E" and is measured in pascals (Pa) or newtons per square meter (N/m²).
 2. How is Young's Modulus calculated?
Young's Modulus is calculated by dividing the stress applied to a material by the strain it produces. The formula is given as E = σ/ε, where E is Young's Modulus, σ is the stress applied to the material, and ε is the strain produced.
 3. What is the significance of Young's Modulus?
Young's Modulus is significant because it provides valuable information about a material's mechanical properties. It helps engineers and scientists understand how a material will behave under different conditions of stress and strain. It is particularly useful in designing structures and predicting their response to external forces.
 4. How does Young's Modulus differ for different materials?
Young's Modulus varies for different materials due to their inherent properties. Some materials, such as steel, have a high Young's Modulus, indicating that they are very rigid and resist deformation under stress. In contrast, materials like rubber have a low Young's Modulus, meaning they are more flexible and prone to deformation.
 5. Can Young's Modulus be used to compare the strength of different materials?
No, Young's Modulus should not be used to directly compare the strength of different materials. While it provides information about a material's stiffness, it does not take into account other factors such as ultimate tensile strength or toughness. Strength is a separate property that should be evaluated independently when comparing materials.
