Questions & Step-by-Step Solutions

What is the maximum bending moment in a simply supported beam with a central point load?
  • Step 1: Understand the setup. You have a beam that is supported at both ends (this is called a simply supported beam).
  • Step 2: Identify the load. There is a single point load applied at the center of the beam.
  • Step 3: Know the variables. Let 'W' be the magnitude of the point load and 'L' be the length of the beam.
  • Step 4: Use the formula for maximum bending moment. The formula for the maximum bending moment (M) in this case is M = WL^2/8.
  • Step 5: Plug in your values. If you know the values of W and L, you can calculate M using the formula.
