Required Practical: The Young Modulus | AQA A Level Physics ...
The aim of the experiment is to measure the YoungModulus of a metal in the form of a wire. This requires a clamped horizontal wire over a pulley. This experiment can also be done with a vertical wire attached to the ceiling with a mass attached. Variables. Independent variable = Force (or load) (N) Dependent variable = Extension (m)
Experiment 3 – Young's Modulus of a Wire - Studocu
Experiment 3 – Young’s Modulusof a Wire Aims: 1. To determine the Young’smodulus of a steel wire. Theory: Figure 1: Stretching of a wire. If we apply a force, F, to the end of a wire of initial length l and cross-sectional area A, producing. a strain, Δl l, theory predicts that provided the elastic limit is not exceeded: F A =E. Δl l

To measure the Young Modulus of a metal in the form of a wire requires a clamped horizontal wire over a pulley (or vertical wire attached to the ceiling with a mass attached) as shown in the diagram below
Young Modulus Experiment (6.1.6) | CIE A-Level Physics Notes ...
1. Preparing the Wire: Inspect the wire for any imperfections or irregularities. Measure the diameter at multiple points using the micrometre screw gauge to ensure uniformity and calculate the average diameter for accuracy. 2. Mounting the Wire: Securely fix one end of the wire to a stable support.
An experiment to measure the Young's Modulus - Cyberphysics
An experiment to measure the Young's Modulus To minimise errors the control wire is the same length, diameter and material as the test wire. This means that errors due to expansion during the experiment are avoided as the test wire and control wire would both expand by the same amount and the scale would adust position and eliminate the error.
Measurement of the Young modulus - schoolphysics
The Youngmodulus may be measured for a material in the form of a wire using the apparatus shown in Figure 1. Two identical wires are hung from a beam; a scale is fixed to one wire and a mass hung on the end to remove kinks in it.
Practical 1P3 Young's Modulus and Stress Analysis
The practical involves applying loads to a beam and measuring the resultant strains as a means to establish the Young’s modulus ( ), Poisson ratio ( ), and Shear modulus ( ) of the material from which the beam is made. The device used to measure strain is the electrical resistance straingauge.
