Why Is My Gradient Too Small in the Young's Modulus Experiment?

Click For Summary
SUMMARY

The discussion centers on the issue of obtaining a small gradient in a Young's Modulus experiment involving a steel bar fixed at both ends with a mass applied at the center. The participant, Matt, is measuring the depression of the bar and plotting a graph of depression versus mass to calculate Young's Modulus. Despite following the practical manual, the gradient remains unexpectedly low, prompting a request for assistance in identifying potential errors or improvements in the experimental setup.

PREREQUISITES
  • Understanding of Young's Modulus and its calculation
  • Familiarity with graphing techniques for experimental data
  • Knowledge of material properties of steel
  • Experience with experimental physics setups
NEXT STEPS
  • Review the principles of Young's Modulus and its experimental determination
  • Investigate potential sources of error in measuring depression in the steel bar
  • Learn about the effects of mass distribution on the results of the experiment
  • Explore techniques for improving measurement accuracy in similar experiments
USEFUL FOR

Students and educators in physics, particularly those conducting experiments related to material properties and elasticity, as well as anyone involved in experimental design and analysis in materials science.

I was doing an experiment on Youngs Modulus, the set up is a steel bar fixed on both ends an a mass put on the centre. Measuring the depression and then drawing a graph of depression vs mass. then using the gradient of to get Youngs Modulus. And my peoblem is the gradient is hust too small, yet according to my practical manual is suppossed to give me the correct answer, pliz help is it possible ? Because i just can't seem to get it

Can you provide more details and your attempt at the solution?

Thanks
