HARDWARE
The Bending Stress in a Beam hardware consists of high-quality teaching apparatus for investigation of stress distribution across the section of a beam. Used at many academic levels, this educational equipment gives students an appreciation of converting strains to stresses, strain gauges, second moment of area, the neutral axis, and the bending equation.
To perform bending stress in a beam experiments, students use an electronic load cell to load a T-section beam. Strain gauges and a digital strain bridge measure the strain.
The equipment includes a lead for connection to a Digital Force Display (STR1a), strain gauges and dummy gauges, 16-way digital strain bridge, aluminium test beam, vernier, a lecturer guide and a student guide.

VIRTUAL EXPERIMENTS
The Bending Stress in a Beam Virtual Experiments Software enables computer simulation of experiments, working with or without the Structures teaching hardware. It expands the scope of experimentation beyond the limits of the hardware, allowing students to select the shape of the beam and the Young's modulus of the beam material.
Digital displays show all the strains at the same time to further assist students' understanding. During experiments the software simultaneously displays a bending moment diagram. Students can visualise, tabulate and graph data, reducing the time required for students to obtain, process and present results. This allows students to realistically, efficiently and conveniently investigate and compare the properties of a wide selection of beam types.
