Description
The experiment hardware fits onto a Structures Test Frame. To load the arch, students fi t masses on weight hangers to set positions along the arch span. Both ends of the arch are fixed. At one end of the arch, a moment arm rests on a load cell. This measures the fixed moment reaction. At the other end, a load cell measures the horizontal thrust. The equipment includes leads to connect the load cells to a Digital Force Display. The lecturer guide provides details of the equipment including sample experiments results. The student guide describes how to use the equipment and gives experiment procedures. For extra ‘virtual’ experiments, we can supply the optional Structures Software (STRS), 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. Refer to the Structures Software datasheet for full details. For automatic data acquisition of your experiment results, we can supply the optional Automatic Data Acquisition Unit. Supplied as standard with the Structures Software that displays and logs your experiments results and gives the extra virtual experiments. Refer to the datasheet for full details.
Learning outcomes
- Shear force variation with an increasing point
- Demonstration of the characteristics of a fi xed arch
- Examination of the relationship between applied loads, horizontal thrust and fi xing moment produced from a fixed (thus redundant in three degrees) arched structure.
- Comparison of behaviour to simplified theory based on the Secant assumption.
