WebA 5 m long aluminium wire (Y = 7 × 10 10 N m − 2) of diameter 3 mm supports a 40 kg mass. In order to have the same elongation in the copper wire (Y = 12 × 10 10 N m − 2) of the same length under the same weight, the diameter of the … WebStronger bonds generally result in higher stiffness; copper has relatively strong bonds due to its metallic bonding, (strong interactions between the metal ions and sea of delocalised electrons) so it has a fairly high young’s modulus value of 110-128 GPa.

WebThere are almost 400 different copper alloys depending on the commercial product made; rods, plates, sheets, strips, tubes, pipes, extrusions, foils, forgings, wires, and castings … WebTo take measurements of a long wire to determine the Young modulus for copper The wire will be under tension so safety spectacles should be worn. Some masses are … michael roberto books

WebLong copper wire Tape Metre ruler Work bench 100 g masses Pulley Method 1. Measure the diameter of the wire in 3 different places using a micrometer and record these ... As the Young modulus = stress/strain, the gradient of the line of best fit is equal to the Young modulus of copper Safety You MUST wear protective eyewear, as if the wire snaps ... WebYoung's modulus is given by the gradient of the line in a stress-strain plot. In the experiment in the video above, we measured the Young’s modulus of some copper wire which does not extend very much. So a fiducial … WebPrediction: I predict from general knowledge that constantan will be able to hold more weights then the copper wire as I believe that the constantan wire will have a higher young’s modulus simply because of the fact that constantan is an alloy and copper is a metal. Constantan is made up of 60% of copper and 40% of nickel. michael roberts auctioneer limerick
