Making Sense of Data: Young's Modulus Of a Metal and An Alloy Aim: - To draw the stress- strain graphs for a metal and an alloy, calculate the Young's Modulus for both metal and alloy and to discuss the physics. A contrast will be made between both materials relating to their stiffness. More details given below: Plan: - Above is a diagram of the set-up used to obtain the results. A micrometer was used to measure the diameter of the wire. A 1m Rule was used to measure the length of the wire. To carry out the experiment, first set up the equipment as shown above. Apply a unit weight of 200g onto the hook each time and take a measurement of the distance between the staring point and the present point of the marker (overall extension). Repeat the experiment 3 times for each metal. MEASUREMENTS: Copper Constantan Length of wire: 2.10m 2.10m Area...
