Question: For a simply supported beam with a point load at the center, what is the maximum bending moment?

Options:

  1. WL/4
  2. WL/2
  3. WL
  4. 0

Correct Answer: WL/2

Solution:

The maximum bending moment for a simply supported beam with a point load at the center is given by M = WL/4, where W is the load and L is the length of the beam.

Questions & Step-by-Step Solutions

For a simply supported beam with a point load at the center, what is the maximum bending moment?
  • Step 1: Identify the type of beam. In this case, it is a simply supported beam.
  • Step 2: Determine the point load (W) applied at the center of the beam.
  • Step 3: Measure the length (L) of the beam from one support to the other.
  • Step 4: Use the formula for maximum bending moment, which is M = WL/4.
  • Step 5: Plug in the values of W (the load) and L (the length of the beam) into the formula.
  • Step 6: Calculate the maximum bending moment (M) using the values from Step 5.
  • Bending Moment – The bending moment at a section of a beam is a measure of the internal moment that induces bending in the beam due to external loads.
  • Simply Supported Beam – A simply supported beam is a beam that is supported at both ends and can freely rotate, allowing for bending under load.
  • Point Load – A point load is a load that is applied at a single point on the beam, which creates a concentrated force.
  • Maximum Bending Moment Calculation – The maximum bending moment for a simply supported beam with a point load at the center can be derived from static equilibrium and is typically calculated using the formula M = WL/4.
