What is the Young Modulus of Nylon Rope?

Click For Summary
SUMMARY

The Young's Modulus of nylon rope is a critical factor in understanding its stress-strain behavior, which can be graphed to illustrate material stiffness. The Young's Modulus (YM) is defined as the ratio of stress to strain, and accurate values can be found online or obtained through practical experiments. For nylon, conducting an experiment with weights can provide empirical data to determine its YM. Comparatively, nylon's YM is lower than that of carbon fiber (125 GPa) and higher than wood (11 GPa), indicating its relative stiffness.

PREREQUISITES
  • Understanding of stress and strain concepts
  • Familiarity with Young's Modulus calculations
  • Basic experimental design skills for material testing
  • Knowledge of graphing techniques for data representation
NEXT STEPS
  • Conduct a practical experiment to measure the Young's Modulus of nylon rope
  • Research the stress-strain curves of various materials, including nylon
  • Learn about the implications of Young's Modulus in engineering applications
  • Explore the differences in Young's Modulus among materials like carbon fiber and wood
USEFUL FOR

Students in materials science, engineers involved in material selection, and anyone interested in the mechanical properties of nylon rope.

Homework Statement


The problem is that I do not have a way of making a nylon rope young modulus stress/strain graph I did not know is anyone would be able to help me obtain the information on the stress and strain or if your feeling really nice make me up a graph!

young modulus = stress
strain


thankyou to anyone who comes out with this answer
 
Physics news on Phys.org
I do not get what you are supposed to do...just draw a stress vs. strain graph for a nylon rope? As in get accurate values and draw or just make a general shape?
 
Whats this part of? You should be able to find values for the young modulus online (gradient of your graph) and I *think* it goes through zero.
If its a practical exercise or part of coursework, then do the experiment.. hehe.
 
A change of subject!

this is a bit of a change of question but last night I was a tad tired and didn't quite ask the right qestion. what I am trying to say is how do you work out how much a rope will hold if you fell off a drop of say 40m? I assume this is to do with young's modulus but I have trawlled the internet trying to find and answer

thanks
 
As YM is the same for any shape/size of material, why don't you conduct as experiment with the nylon and weights? YM will tlel you how stiff the material is i.e. the high the YM, the stiffer the material. E.g. carbon fibre has a YM of about 125 GPa, and it is very stiff in comparison to wood, which has a YM of about 11GPa.
