How do you determine the magnification on the graph sheet of a tensometer?

To determine the magnification on the graph sheet of a tensometer, measure the distance between two points on the sheet and compare it to the actual distance represented by those points in the material being tested. The magnification can be calculated using the formula: Magnification = Distance on graph sheet / Actual distance. Ensure that both measurements are in the same units for accuracy. This ratio indicates how much larger or smaller the graph representation is compared to the real-life dimensions.
