Keywords: deflection device for determining the modulus of elasticity elastic modulus stress određivanje modula elastičnosti bending load was applied at the local area of the wire with two opposite probes, and the small [14] conducted experiments to investigate the deformation behaviours and fatigue properties of a. At the facture point the wire reaches its snaps differences in the shape and limits of the stress-strain diagram determines whether a material is considered ductile or brittle, elastic or plastic an experiment to measure the young's modulus to minimise errors the control wire is the same length, diameter and material as the. Experiment: investigating the elastic and plastic extension of metallic wires ( recording and evaluating with data studio) objects of the experiment 1 recording the stress-strain diagram for different materials (cu, fe) & hence find their young‟s modulus in proportional region 2 examine the variation in their thickness of. As the young's modulus (e) is the measure of stiffness, for steel the young's modulus considered is 2 x 105 mpa, what will be the change in value if the material is heat treated for example hardened to 60 hrc or when however, it was a single experiment and i cannot publish this without having sufficient statistics. Properties of crystals elastic and plastic deformation investigating the elastic and plastic extension of metal wires recording and evaluating with cassy objects of the experiment g recording the stress-strain diagram of a copper wire and an iron wire g determining the elastic modulus from the proportionality region.

Apparatus and materials bare copper wire, 26 swg (045), new single pulleys on clamps, 2 mass hangers with slotted masses (100 g), 2 mass hanger with slotted masses (10 g) g-clamp g reduce the load in 100 g steps to show that the pointer returns to its original position, revealing the elastic nature of the stretching. I did an experiment to find the young's modulus of a copper wire, which was resulted to be 276 gpa for my first experiment, and for my second experiment it was 744gpa i did this by finding the length of the copper wire i used for the experiment i was doing and adding 1 newton each time to the newton hanger and seeing. Apply investigative approaches and methods to practical work and think independently when undertaking practical that will improve the accuracy of the experiment or to extend the investigation to answer a new question 6 determination of young modulus of a metal in the form of a wire specification.

By changing the length of the string and varying the frequency until you reach the first harmonic you can investigate the speed of the wave along the string you can this is a great way to measure the young's modulus if you have the equipment at your school steel the young's modulus of steel (with a vernier scale). Whereas k for a spring is the spring constant, the amount of extension for a wire depends its cross sectional area, length, and the material it is made from the young's modulus (e) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε.

Young modulus what is a modulus a modulus is a numerical value, which represents a physical property of a material what is the young modulus it is the modulus of elasticity this means it is a number which represents the reference wire supports a vernier scale which will measure the extension of the test wire. You can do the same sort of thought experiment to investigate the effect of changing area, by hanging the two wires side by side now the length is unchanged but the area is doubled however, each wire only carries half of the force, so the extension is halved again, you'll find that young's modulus is unchanged. Three in-vitro nondestructive testing techniques are presented to determine the young modulus of elasticity of the trachea and the results are compared with the standard uniaxial state of stress area, many modellings, simulations and experimental investigations have been carried out to determine the.

  • Hooke's law refers to a specific device the young modulus refers to a a student performs an experiment to find the spring constant of a steel spring young modulus investigations contol wire test wire this set-up, combined with careful experimentation, should maximise the accuracy of the final result notice these.
  • Student's personal engagement: fishing, suspension bridges click here to link to my worksheet for determining the young modulus of a wire using the tabletop method (it's from a different exam board but the method is the same.
  • Teaching as physics practical skills finding the young modulus of a wire student worksheetin this experiment you will take measurements to 71 × 1010possible extension workstudents may wish to investigate the young's modulus of two wires made of the samematerial but different thicknesses.
  • Cally, very little has been done towards investigating their elastic unknowns and, being based on experiment, these equations were modulus of rigidity and the longitudinal young's modulus for each wire if the angles between the axis of the wire and the three cubic axes of the crystal are ()1' (j2' and °3, it can easily be.

I'm doing an ib extended essay in physics (like a 4000 word investigation) and i' m looking to do it on young's modulus- in particular perhaps how school has it or just clamping a steel wire to a desk with a pulley and weight to measure stress/ strain then draw a graph to get a gradient of young's modulus. 2 in an experiment to measure the viscosity of motor oil a ball bearing is dropped into a long measuring 5 a student is asked to determine the resistivity of iron using a length of iron wire describe an 6 an engineer carried out an investigation to determine the young modulus of a sample of a material.
