Strain Gauges. c/o Elizabeth . P. hillips. Then & Now: Under Stress. This link is about how measuring stress has changed over the years to the present day.. These strain gauges are use to measure the amount of stress an airplane can handle until it fails. Before strain gauges were invented, people would put sand or themselves on the wing until it broke. "As you push up on a wing, our analysis says it ought to deflect a certain amount, so we measure [with strain gauges] the amount it actually deflects," says Mark Jenks. .

"Of bending of the springs: If a straight spring is bent, it is necessary that its convex part become thinner and its concave part, thicker. This modification is pyramidal, and consequently, there will never be a change in the middle of the spring.

Stress-Strain Diagram . Suppose that a metal specimen be placed in tension-compression testing machine. As the axial load is gradually increased in increments, the total elongation over the gage length is measured at each increment of the load and this is continued until failure of the specimen takes place. Knowing the original cross-sectional area and length of the specimen, the normal stress σ and the strain ε can be obtained. The graph of these quantities with the stress σ along the y-axis and the strain ε along the x-axis is called the stress-strain diagram. The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium carbon structural steel. . Precipitation can be divided into three categories. . based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or . ice. Mixtures of different types of precipitation, including types in different categories, can fall simultaneously. . 02/02/16. 2. Mechanical Measurement Laboratory. EN/MME/EDM . M. Guinchard / P. .
