I used the sample data given by Edexcel. They claim it’s for copper but if that were true it would give an E of 117GPa or thereabouts… so I suspect it is either not copper or there is a large error built in! Unless I have made an error in my calculations but if so, I can’t spot it!
what material did you use to get these readings? and thank you this video is very helpful!

How did u calculat area
Area =4"pie"r^2?
Yes, for the cross sectional area of a wire. Beware questions though where it’s of some other shape. Regardless, you need cross-sectional area.
@@nutshellphy what are other shapes could come? can u mention all the volumes, areas we need to know ? thankyou in advance!
Cuboids mostly so just width x depth. Nothing too tricky, just a matter of paying attention.
