Features

• High-quality structures teaching module for students of mechanical, civil and structural engineering  
• Allows safe and practical experiments into bending stress in a beam 
• Realistic and verifiable experiment results 
• Optional Tesca’s SCI-CALS Structures Software package for extra ‘virtual’ experiments that  simulate and confirm  the results from your hardware and allow extended experiments  
• Optional DAQ Structures Software package for automatic data acquisition and virtual experiments  
• Ideal for classroom demonstrations, or students working in pairs or small groups

Tesca Bending Stress in a Beam Apparatus allows adjustment of a load cell that  bends the beam and, when connected to the optional Digital Force Display, it measures the bending  force (load). Strain gauges and a digital strain bridge measure the strains in the beam. Dummy strain  gauges compensate for temperature variation and balance  
the strain bridges. The equipment includes a lead for connection to the Digital Force Display.  The lecturer guide provides details of the equipment including sample experiment results. The  student guide describes how to use the equipment and gives experiment procedures.  

For extra ‘virtual’ experiments, Tesca’s SCI-CALS Structures Software, available for use on a  suitable computer. The virtual experiments simulate the tests that you do with the hardware. They  also extend the choice of tests than that available using only the hardware, for example: higher loads,  uniform loads or different test specimens. This extends the student’s learning experience.  

For automatic data acquisition of your experiment results, DAQ, the optional Automatic Data 
Acquisition Unit, that displays and logs your experiment results and gives the extra virtual  experiments.
