Young Modulus case study

Young's Modulus of fishing lines Introduction In this assessment, I am going 'to explore the properties of fishing line which are considered by manufacturers when designing them.'1 Investigation I am going to be concentrating on the types of fishing line used. I am going to measure the Young's Modulus of each line to determine their tensile strength and resistance to stretching. In order to do this, I am going to perform an experiment that will measure the YM of each line. How does it relate to the case study? The results from the experiment will give me an idea of their capability of being useful fishing lines. Define: Young's Modulus - 'the stress and strain of a material are proportional to each other. ...read more.


Add more mass, and observe the marker move in order to determine the change in length. Continue until the line breaks. Using the recorded results, determine each line's Young Modulus using the formula. Fishing Lines and their properties The 3 main types of line used: braided dacron, monofilament and fluorocarbon. Braided Dacron: 'high tensile strength, high resistance to stretching, both wet and dry...'3 Monofilament: one source states that 'monofilament fishing line due to its chemical properties is stiff with tension'.4 Fluorocarbon: '...don't lose their strength after prolonged immersion in water: as a result they have much less elongation (stretch) under load.'5 We must take into consideration that different companies produce varying quality of lines for each type of line; therefore we cannot assume that all are the same. ...read more.
