Q: What is the unit of Young's modulus?
Solution:
Young's modulus is defined as stress divided by strain and is measured in Pascals (Pa).
Steps: 5
Show Steps
Step 1: Understand that Young's modulus is a measure of how stiff a material is.
Step 2: Know that Young's modulus is calculated by dividing stress by strain.
Step 3: Learn that stress is defined as force per unit area, which is measured in Pascals (Pa).
Step 4: Recognize that strain is a dimensionless quantity (it has no units).
Step 5: Since Young's modulus is stress (in Pascals) divided by strain (dimensionless), the unit of Young's modulus is also in Pascals (Pa).
