There is a small hot spot in the top-left corner. Young’s modulus is the ratio of tensile stress to tensile strain. Save my name, email, and website in this browser for the next time I comment. Questions 1. Our use of materials characterises our history (Stone Age, Iron Age, etc.) Add to wish list In stock Ask a question. University. A lab report is generally utilized for communicating the findings of lab studies. Part 1: To investigate the relationship between... View more. It’s a summary of what you have actually done. Purpose This experiment is designed to determine Young’s modulus for a wire when it is stretched. In solid mechanics, Young’s modulus is defines as the ratio of the longitudinal stress over longitudinal strain, in the range of elasticity the Hook’s law holds (stress is directly proportional to strain). It is a measure of the stiffness of a material; however, in practice, other properties of materials, scientists and engineers are often interested in, such as yield stress, have more influence on the selection of materials for a particular purpose. 12/03/2017 2 VIDEOS ... the experiment are avoided as the test wire and control wire would both expand by the same amount and the scale would adjust position We used the concept of Hooke’s Law, which states that in a certain range, the strain or deformation of a material is proportional to the stress applied to it. length and surface area). The hardness and elasticity of the material are profoundly affected. The first experiments that used the concept of Young's modulus in its current form were performed by the Italian scientist Giordano Riccati in 1782, pre-dating Young's work by 25 years. They are used to summarize and interpret the data gathered. 293851) and Scotland (no. Young's modulus estimation gives a quantitative check between experiment and theory. Nvis 6040 Young`s Modulus Setup is a complete system used to determine Young`s Modulus of Elasticity of materials. in the class.

Rather than using a note card to split the single beam into two coherent beams, a carbon-coated glass slide with two closely spaced etched slits is used. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. 2. and is calculated using the formula below: Our aim is to determine the Young’s modulus of elasticity of the material of a given wire using Searle’s apparatus. The Young Modulus is named after Thomas Young (1773 to 1829) who was a British polymath, contributing to our understanding of optics, physiology, and Egyptology, among other fields. Light fr… Young’s Modulus. Note that in the set up above, the sample is at an angle to the ruler – a source of systematic error. Comments. Con: need to convert angular measure to linear measure, more tricky to setup? Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode. “), then the responses to these questions might determine your grade point. 16-19. It is helpful if students can learn to find their way around tables of material properties. Young’s modulus, numerical constant, named for the 18th-century English physician and physicist Thomas Young, that describes the elastic properties of a solid undergoing tension or compression in only one direction, as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length. Ask students to identify the quantities to be measured, how they might be measured, and so on. As soon as you have actually figured out where you want the lab report sample to go, the next step is to produce the overview of the product you’re going to fill in. Theory. 14-16.

Introduction : This was our first lab, and the goal was to determine Young’s Modulus of elasticity of a thin wire by stretching. en Change Language. Our Objective. Measure the gradient of the straight portion of the graph and use this to calculate the Young modulus for the copper. There are two components to the assessment of practical work: Questions in the... For 16-19 Young's Modulus, Elastic Modulus Or Modulus of Elasticity takes the values for stress and strain to predict the performance of the material in many other scenarios, such as Beam Deflection. There is a second hot-spot in the lower-right corner of the iFrame. If at the lower end of wire of length ‘L’ and cross-sectional area of ‘A’ a load of ‘m’ is pressed and if the length increases by l, then; Method For the procedure, see lab manual (PC142 Lab Manual, Winter 2017). Feedback. The reference wire supports a vernier scale, which will measure the extension of the test wire. good and superb. Rigid bodies do not bend, stretch or squeeze when forces act on them. 4 mins read. How do I use my lab report sample?

Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode. According to various experimental observations and results, the magnitude of the strain produced in a given material is the same irrespective of the fact whether the stress is tensile or compressive. Result Precautions. Young’s Modulus. Procedure. The Young's modulus is the property less dependent of the characteristics of the coatings (microstructure and morphology), but is strongly dependent of the chemical composition. Read free for days Sign In; Much more than documents. Both the wires should be supported from same rigid support. Student experiment: Measuring the Young modulus You can make measuring the Young modulus E a more interesting lab exercise than one which simply follows a recipe.

Young’s modulus, used as a numerical constant. ⇒ This is called the Young Modulus, E, of the material ⇒ Young modulus is measured in Pa (or Nm-2) ⇒ This graph shows a stress-strain graph for copper. In the experiment in the video above, we measured the Young’s modulus of some copper wire which does not extend very much. Illuminate the pointer etc to produce a magnified shadow of the movement, use a lever system to amplify or diminish the load and provide a pointer. At the end, you could show the standard version of this experiment (with Vernier scale etc.) Your report should include the findings and observations of your experiments, the outcomes acquired from the experiments, and any additional information that will work for readers. Academic year. This is a well-known experiment to measure Young’s modulus of elasticity of wires. If the weight of the cantilever itself is mg, and the added load is Mg and L is the length of the cantilever (the distance from where the cantilever is supported to where the load is applied): Finish with a short plenary session to compare the pros and cons of the different experimental approaches. Measure the gradient of the straight portion of the graph and use this to calculate the Young modulus for the copper. Documents. The initial longitudinal Young modulus E 1 0 is determined directly using a tensile test on the fabric as shown in Fig. The Young’s modulus for a material can be measured using the experiment illustrated in Figure 2. Young’s modulus Experiment Young’s modulus Experiment. A measure of stiffness that is independent of the particular sample of a substance is the Young modulus E. Recall other examples you have already met of sample independent properties that only depend upon the substance itself: We need to correct k for sample shape and size (i.e. To gain knowledge in use of the instrumentation to conduct the above investigation. Students should wear eye protection, provide safe landing for the load should sample break, e.g. Theory. Sign In Join. Would you like to write for us?
