Questions & Step-by-Step Solutions

What is the Young's modulus of a material if a stress of 200 MPa produces a strain of 0.01? (2021)
  • Step 1: Understand the formula for Young's modulus, which is E = Stress / Strain.
  • Step 2: Identify the given values: Stress = 200 MPa and Strain = 0.01.
  • Step 3: Substitute the values into the formula: E = 200 MPa / 0.01.
  • Step 4: Perform the division: 200 MPa divided by 0.01 equals 20000 MPa.
  • Step 5: Convert 20000 MPa to a simpler form: 20000 MPa is the same as 2000 MPa.
