Original Length of Mild Steel test bar given Total Extension Solution

STEP 0: Pre-Calculation Summary
Formula Used
Initial Length = (Total Extension-Total Elongation)/Coefficient of Extension
l0 = (x-δL)/z
This formula uses 4 Variables
Variables Used
Initial Length - (Measured in Meter) - Initial Length before the application of load.
Total Extension - (Measured in Meter) - Total Extension is defined when an object increases in length, and compression happens when it decreases in length.
Total Elongation - (Measured in Meter) - Total Elongation of a bar is defined as the elongation due to its own weight.
Coefficient of Extension - Coefficient of Extension refers to the coefficient used in unwin equation of elongation.
STEP 1: Convert Input(s) to Base Unit
Total Extension: 120 Millimeter --> 0.12 Meter (Check conversion here)
Total Elongation: 70 Millimeter --> 0.07 Meter (Check conversion here)
Coefficient of Extension: 0.6 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
l0 = (x-δL)/z --> (0.12-0.07)/0.6
Evaluating ... ...
l0 = 0.0833333333333333
STEP 3: Convert Result to Output's Unit
0.0833333333333333 Meter -->83.3333333333333 Millimeter (Check conversion here)
FINAL ANSWER
83.3333333333333 83.33333 Millimeter <-- Initial Length

8 Measurement of Ductility of Metal Calculators

Load given Brinell Hardness Number
Go Load = (Brinell Hardness Number*pi*Steel Ball Diameter*(Steel Ball Diameter-sqrt(Steel Ball Diameter^2-Depression Diameter^2)))/2
Total Extension given Area of Mild Steel bar
Go Total Extension = Coefficient of Elongation*sqrt(Cross-sectional Area of Specimen)+(Coefficient of Extension*Initial Length)
Percentage Elongation of Mild Steel Test Bar
Go Percentage Elongation = ((Initial Length-Length of Test Bar at Fracture)/Length of Test Bar at Fracture)*100
Local extension of mild steel bar
Go Local Extension = Coefficient of Elongation*sqrt(Cross-sectional Area of Specimen)
Original Length of Mild Steel test bar given Total Extension
Go Initial Length = (Total Extension-Total Elongation)/Coefficient of Extension
Total Extension of Mild Steel Test Bar
Go Total Extension = Total Elongation+Coefficient of Extension*Initial Length
Area of Mild Steel bar given Local Extension
Go Cross-sectional Area of Specimen = (Local Extension/Coefficient of Elongation)^2
Gross area design strength for steel
Go Design Strength = Gross Area of Cross-Section*Yield Strength/1.1

Original Length of Mild Steel test bar given Total Extension Formula

Initial Length = (Total Extension-Total Elongation)/Coefficient of Extension
l0 = (x-δL)/z

When does the elongation of a material occur?

Elongation is a measure of deformation that occurs before a material eventually breaks when subjected to a tensile load. As the latter is applied, an increase in length and a uniform reduction in cross-sectional area take place, while the material maintains a constant volume.
