Toshiba 44295004000 DEVELOPER, BLACK, 120K YIELD

this video will demonstrate how to calculate the yield stress and ultimate tensile stress of a sample of low carbon steel using the force extension graph yield stress is calculated by dividing the Forsett yield by the original cross sectional area of the test sample the image shows a typical test sample which is cylindrical in shape the diameter of the sample would be measured before the test commences and it is very simple to calculate the cross sectional area of the cylinder using PI R squared this is a typical force extension graph for a low carbon steel sample showing a clearly defined yield point on the curve to calculate the force it yield simply draw a line parallel with the x axis from the yield point until it intersects with the y axis looking at the scale on the y axis it is not possible to estimate the force in Newtons so we need to measure the axis to obtain an accurate valu
