LAB 2 - Essay ExampleSpecifically, the most common and accepted manner of measuring gallop is using the electrical resistant strain gage.The strain gage is a drawn conductor made of a wire or a metallic foil that is in a grid-like pattern. In particular, the grid-like pattern maximizes the amount of strain in the parallel direction. The experiment uses a conductor (carrier) that is of keen strips of metallic film placed on a non-conducting substrate material. The wire is to the specimen and facilitates the transfer of the strain from the specimen to the strain gage. Accordingly, the transfer makes a linear change in the electrical metro. Precisely, the electrical resistance of a conducting wire fluctuates when the length of the conductor changes in a process called deformation or stretching. Consequently, the primer of the electrical resistance strain gage is the deformation. Under an ideal situation, the strain gage resistance ranges betwixt 30 to 3 k. Fundamentally, the res istance changes only a fraction of a percent in a full force range of the gauges. For this reason, a higher resistance change causes a changeless deformity to the test specimen. Therefore, a successful use of the strain gauge calls for a measure of modest changes under high
