# Young modulus copper coursework

In United States customary units, it is expressed as pounds (force) per square inch (psi).The extension is directly proportional to the applied force. To further investigate how the material behaves when it is stressed,we define: The stress applied to the wire is defined as the force applied per unit cross-sectional area. Copper can be released into the environment by both natural sources and human actions. The technical definition is: the ratio of the stress (force per unit area) along an axis to the strain (ratio of deformation over initial length) along that axis in the range of stress in which Hooke's law holds.).Strain is "deformation of a solid due to stress" - change in dimension divided by the original value of the dimension - and can be expressed as Elasticity is a property of an object or material which will restore it to its original shape after distortion.If the wire is stretched beyond its elastic limit, it will not return to the original length and will make permanent extensions. So force constant is not a good quantity to compare the stiffness of materials. For a non brittle material, usually there are two stages of deformation before breaking. Also it should not be kept too high from the ground, this may cause the tiles of the floor to break. The sticker should not be placed too close to the pulley. This is to avoid exerting impulse to the wire and making the masses to oscillate. A few apparatus and steps are needed, and it only involves easy calculations.For this experiment, however, a wire was used as a specimen.The Young Modulus for a wire can be measured using this equipment.My teacher says this is a bit basic to get a really good mark and told me there was another method of calculating the Young Modulus which I should do as well and then write my report on which is the most accurate.The Young's modulus directly applies to cases of uniaxial stress, that is tensile or compressive stress in one direction and no stress in the other directions.I have sympathy – I remember harassing my own physics teacher for an idea for my sixth form Physics Investigation!Hello- I am running a simulation of a simple brazed copper assembly; brazed at 1050°C.
