Young's Modulus Investigation A. In this experiment I aim to find a value for the Young's Modulus of a piece of cassette tape. Young's Modulus is a way of expressing how much a certain material is stretched or compressed. For the same material the Young's Modulus is always the same, this can be explained by looking at the way in which we calculate it. Young's Modulus = Stress ? Strain The amount of stress exerted on a material can be calculated by: - Force ? Area Strain is calculated by: - Extension ? Original length To find the Young's Modulus of the cassette tape, I will attach certain weights to the end of the tape and measure the extension caused by each weight. I will also have to determine the cross sectional area and the length of the tape before I attach any weights to the cassette tape. Here is a diagram to illustrate what my...
