Total Extension of Mild Steel Test Bar Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Extension = Total Elongation+Coefficient of Extension*Initial Length
x = δL+z*l₀
This formula uses 4 Variables

Variables Used

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.
Initial Length - (Measured in Meter) - Initial Length before the application of load.

STEP 1: Convert Input(s) to Base Unit

Total Elongation: 70 Millimeter --> 0.07 Meter (Check conversion here)
Coefficient of Extension: 0.6 --> No Conversion Required
Initial Length: 101 Millimeter --> 0.101 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

x = δL+z*l₀ --> 0.07+0.6*0.101

Evaluating ... ...

x = 0.1306

STEP 3: Convert Result to Output's Unit

0.1306 Meter -->130.6 Millimeter (Check conversion here)

FINAL ANSWER

130.6 Millimeter <-- Total Extension

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

Total Extension of Mild Steel Test Bar Formula

Total Extension = Total Elongation+Coefficient of Extension*Initial Length
x = δL+z*l₀

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.

Which is an example of an elongation test?

Mechanical properties are essential in describing the behaviour of a material when a load is applied. Many tests, such as tension, compression, impact, bending, shear, torsion, and hardness tests, are developed in order to observe the response of a material to an applied external force.
