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

[DrMouze]

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

From what you have described, it sounds like you have followed the correct procedure for determining Young's Modulus. However, there are a few factors that could be contributing to your small gradient and incorrect results.

First, make sure that the steel bar is completely straight and not bent or curved in any way. Any deformation in the bar could affect the results.

Secondly, check that the mass you are using is accurate and calibrated properly. A slight difference in mass could also lead to a small gradient.

Lastly, it is possible that there could be external factors affecting your results, such as changes in temperature or humidity. These can also impact the accuracy of your experiment.

I would suggest repeating the experiment a few times to see if you consistently get a small gradient. If so, double check all of your equipment and procedures to ensure they are accurate. If the issue persists, you may want to consult with your instructor or a lab technician for further assistance. Good luck!
