Description

An experimental apparatus to allow students to investigate the important features of a two-pinned arch and to illustrate the use of arches where the footings are hard especially in the horizontal direction.

The experiment hardware fits onto the Structures Test Frame (STR1, available separately). Students use masses on weight hangers to apply various loads to the arch at set positions along its span.

One end of the arch is pivoted, the other end rolls against a load cell. When connected to a Digital Force Display (STR1a, available separately), the load cell measures the thrust reaction. The equipment includes a lead to connect the load cell to a Digital Force Display (STR1a). 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, TecQuipment can supply the optional TecQuipment Structures Software (STRS), for use on a suitable computer. The virtual experiments simulate the tests you can perform with the hardware. They also extend the choice of tests beyond 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, TecQuipment can supply the optional Automatic Data Acquisition Unit (STR2000). Supplied as standard with the STR2000 is TecQuipment’s Structures Software that displays and logs your experiment results and gives the extra virtual experiments.

Key features:

  • High-quality structures teaching module for students of mechanical, civil and structural engineering
  • Allows safe and practical experiments into two-pinned arches
  • Realistic and verifiable experiment results
  • Optional TecQuipment’s Structures Software package for extra ‘virtual’ experiments that simulate and confirm the results from your hardware and allow extended experiments
  • Optional STR2000 unit with TecQuipment’s Structures Software package for automatic data acquisition and virtual experiments
  • One of many interchangeable experiment modules from TecQuipment’s modern, flexible and cost effective structures teaching system
  • Ideal for classroom demonstrations, or students working in pairs or small groups

Learning outcomes:

  • Demonstration of the characteristics of a two-pinned arch
  • Examination of the relationship between applied loads and horizontal thrust produced from a redundant (in one degree) arched structure
  • Comparison of behaviour to simplified theory based on the Secant assumption
