Youngs Modulus Experiment
1 Firstly determine the vernier constant of the instrument. Cantilever construction allows for overhanging structures without external bracing.
Schoolphysics Welcome
Up to 3 cash back Youngs modulus is ML1T2.
. Youngs modulus of a material is its fundamental property that remains unchanged. Modulus or modulus of longitudinal elasticity or stretch modulus of the material of the wire. So Material A will have higher Youngs modulus than Material B.
Strain data for a test sample in the elastic region. Physical injury if the wire breaks. Table set up for data collection.
When a spring or a rubber band is stretched and released they come back to their original size shapeThis physical property of a material called elasticity. The slope of the Stress strain curve in elastic region is called Youngs Modulus. The Young modulus is often regarded as the quintessential material property and students can learn to measure it.
Set up diagram or description 4. The Stress-strain diagram The stress strain relationship of any material is of primary importance as it gives a good idea of the mechanical behaviour of the material in real life conditions. Up to 24 cash back the experiment are avoided as the test wire and control wire would both expand by the same amount and the scale would adjust position.
Background information what is Youngs Modulus how do we use a stress strain curve to determine it etc 3. It is a measure of the stiffness of a material. This is generally accomplished using the tension-compression tests.
It is defined as the limit for small strains of the rate of change of stress with strain. A box containing old clothsponges etc. Objective To study the stress and strain of the material to study the various region and stressstrain behavior using the stress-strain diagram to determine the Youngs Modules of Elasticity and to study the ductile behavior of the material.
2 Diameters of the experimental wire at different points are measured by a screw gauge and the average value of. In this video I go through an AQA Physics A Level Required Practical that uses a Youngs Modulus experiment to calculate the Youngs Modulus of steel wire. Youngs modulus Gradient of the straight-line section of the stress-strain curve y 2 -y 1 x 2 -x 1 where x 1 y 1 and x 2 y 2 are coordinates of two points on the straight line.
But it is dependent on material temperature. To determine the youngs modulus of wood using the cantilever method. Activity time 170 minutes.
--2 Thus y Tensile stress Mgnr Mgl Tensile strain iill nr2iil 1 The wire whose Youngs modulus is to be determined passes over a small -cyltnder--which-is free--to rotate about a horizontal axis Fig. The stress-strain graph for two materials is illustrated in Figure 1. A cantilever is a beam supported on only one end.
Several runs will be taken for the same sample to calculate the average value of Youngs Modulus for the material. Experiments to show Youngs modulus Wire Micrometre Pulley Metre ruler Caliper Weights Clamp Wooden block Bench. 188313- 183887 00814096- 00042.
The beam carries the load to the support where it is resisted by moment and shear stress. Material A is stiffer than material B as a higher stress is needed to produce the same amount of strain. When subjected to external forces a solid body may deform.
Students should wear eye protection and should provide safe landing for the load should sample break eg. Introduction Through this Youngs Modules experiment we able to find the elastic limit and elastic modules to record. Select the material of the wire whose Youngs modulus you want to determine by choosing steel from the rectangle box on the top left Arrow-1 of Fig.
Then by applying a load in the experimental wire it is. However in practice other properties of materials scientists and engineers are often interested in such as yield stress have more influence on. Click on the executable file Youngs Modulus_vle then a window will open as shown in Fig.
The Youngs modulus elastic modulus is the measurement of the stiffness of a given material. At first unzip Youngs Modulus_vle zipped File. In this lab students will collect stress vs.
Besides using the stress and strain graphs the Youngs Modulus of any material can also be determined by using the deflection of the material beam when subjected to load.
