Why is it necessary to state the gauge length when reporting the percentage elongation?
because want to determine mechanical property of desired region
Does the elongation of the cells in the region of elongation increase the root length?
no
What is Gauge?
Please add to this question.Something to measure things with.
What is the elongation of a bar due to its own weight?
The elongation of a uniform bar of length is double the elongation when applied any external load
How do you calculate elongation in post tensioning?
Elongation is the percentage of the final dimension relative to the initial dimension. For instance; A 1m length of metal is put under a load and is stretched to a final length of 1.5m The elongation of this is 150% because the final length is 150% of the initial length.
How do you calculate percent elongation in materials?
To calculate percent elongation with an equation: [(final length - initial length) / initial length] x 100 = percent elongation On a graph - To calculate percent elongation, draw a line to the x-axis from the point of fracture parallel to the straight line part of the graph. The extension at this point is then divided by the gauge length.
What is the difference between strain and Elongation?
Strain is the measure of length change per unit length. Elongation usually refers to strain under load at failure point.
What do telomerase do?
enzyme that helps in sythesis and elongation of telomere length
How to measure steel elongation?
find it out . It's measured in the lab after a pull test. Steel elongation can be measure manually or using device called extentiometer. To measure elongation of steel manually we must give 2 punch marks on the specimen with specified length (see standard/code such as ASTM, ASME etc for specimen shape and size) addressed L0. After a pull test (tension/tensile test) we measure the distance between that 2 punch marks and addressed L1. Thus, the elongation of the specimen in percentage is ((L1-L0)/L0) x 100%. Measure elongation using extentiometer is lot more easier because we can directly read the result. But this method limited for small elongation measurement only.
Strain formula for cylinder in tensile test?
Strain = Extension (m) / Original length (m)
What does the percentage of elongation of a test piece under a tensile load indicate?
The change in length of a material under loading can be used to calculate the strain the material has undergone. When stress is plotted against strain, the gradient of the straight line portion of the stress strain curve is equal to Young's Modulus, a type of axial stiffness applicable to a material that obeys Hooke's law at stresses below the yield strength of the material.
