I. Topic: Tension testing
2.What is tension test?
Tension test is a fundamental material science test in which a sample is subjected to uniaxial tension until failure. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. Properties that are directly measured via a tensile test are ultimate tensile strength, maximum elongation and reduction in area. From these measurements the following properties can also be determined: young’s modulus, poison ratio, yield strength, and strain hardening characteristics.
3.The tension tester A machine which applies a tensile force (a force applied in opposite directions) to the specimen, and then measures that force and also the elongation: This machine usually uses a hydraulic cylinder to create the force. The applied force is determined by system pressure, which can be accurately measured.

Materials:
1.Specimen made up of aluminum alloy having a round cross section and threaded shoulders which design for serrated grips. 2.Steel marker . 3.Testing machine.(hydraulics)
1.Prepare the specimen required as shown. 2.Mark the sample specimen to establish its original formation. 3.Insert the specimen to the grip holder. Then the sensor grip at the center of the specimen to ensure that there will be no fault action on the test. 4.Start the machine, perform the test, Obsreved. 5.Look at the specimen where in as you can see it starts changing its diameter. 6.Wait until it breaks. 7.Remove the Specimen to the machine.
