Questions & Step-by-Step Solutions

What is the factor of safety for a beam that has a maximum bending stress of 30 MPa and a yield strength of 150 MPa?
  • Step 1: Identify the maximum bending stress of the beam, which is given as 30 MPa.
  • Step 2: Identify the yield strength of the material, which is given as 150 MPa.
  • Step 3: Use the formula for factor of safety (FoS), which is FoS = Yield Strength / Maximum Stress.
  • Step 4: Substitute the values into the formula: FoS = 150 MPa / 30 MPa.
  • Step 5: Perform the division: 150 divided by 30 equals 5.
  • Step 6: Conclude that the factor of safety for the beam is 5.
