Click the down arrow to decrease the applied strain by the Step increment value. Click the up arrow to increase the applied strain by the Step increment value. Set the strain increment value as described above. Click the Set button again (display stops flashing). Use the keypad and the Del button to enter the desired Step value. Click the Set button (display starts to flash). Or open the callipers, return the sample to its original position and choose another sample. Click the sample held in the callipers to use it in the tensile testing machine. Use the Vernier scale to measure the sample width. (In this LITE version you can only select one of the samples). Open the calliper jaws, drag a sample of choice between the jaw and fully close the jaws around it. Click the lower jaw to go to the sample view. Download the file below for the quick guide for the Tensile Testing experiment (requires login) or follow these brief instructions: extrusion to make tubes, beams and bottles drawing to make springs or wires or forging and rolling to shape and harden metals. And it’s not just how a component is used – many manufacturing processes involve changing a component’s shape or response to applied forces, e.g. Elastic materials can be stretched enormously before any permanent change is made and are used in springs and high performance fabrics. Hard materials are used in machines and robots that process and shape other materials and as durable coatings that improve the performance and lifetime of aerospace and bio-implant components. Thin but robust materials are used in touchscreens. Flexible materials are also used in many of these applications. 
Strong and stiff structures are used in vehicles (cycles, cars, trains, aeroplanes, spacecraft), bridges and buildings, sports equipment and bio-implants (e.g.
The range of uses this covers is enormous. Understanding of tensile properties is vital for any application that uses materials structurally, i.e. The ‘tensile’ properties of a material describe its most basic mechanical behaviour – how much does a material stretch when it is pulled and how much of the stretching is permanent? ‘Tensile Testing’ is the process of measuring a material’s tensile properties.
