Bending Stress in a Beam

This product helps students to understand the bending stresses at various positions of a beam section due to a load. Students add loads to an inverted T-section beam held on two supports. Strain gauges at different heights up the beam measure the strains due to the load. A load cell measures the force applied at the mid span of the beam.

This product includes a Vernier caliper for accurate measurement of the beam cross-section.

Learning Outcomes

  • Stress and strain relationship
  • Strain gauges as instruments
  • Finding the neutral axis by experiment and calculation
  • How the beam cross-section dimensions affect the second moment of area (I value) and neutral axis
