Design and Construction of Indigenous Strain Gauge Equipment
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
Strain is an important factor that establishes the mechanical behavior of varieties of metal used in machine development. The strain experienced in a metal is directly proportional to the stress. Equipment such as resistance strain gauge, piezoelectric strain gauge and extensometer are used for measuring strain. These devices are expensive and the costs of maintenance are high, hence the need to develop an indigenous strain gauge that is affordable. This device is simply design for easy application in carrying out materials’ strength experiment by student. The developed indigenous strain gauge has a height of 1.22m and could accommodate samples of 5 to 10 mm diameters with a gauge length of 200mm; couple to it is a transducer to magnify the strain signal for efficient strain calibration. The equipment was able to withstand a load of 1000N. The ratio of deformation (Strain) with reference to load increment correlates with theoretical response.
