i wrote about it the same way too!!1 :good: :good: :good: :good: :good: :good:alphabravocharlie said:You could do it that way. I wrote that use a newton meter for force, ruler for original length and extension, and vernier caliper for area. Then use formula of stress/strain to calculate young modulus. i am not sure this method might be wrong. the graph one seems like a more logical answer.

Its Marking Scheme says students are expected to mention about a Stress Strain graph, one limitation of the experiment and one improvement. Also, micrometer to measure DIAMETER and NOT area of the wire. Meter rule to measure the length of the wire.
yea u r ryt absolutely i solved that young modulus question...not Q 1 though it was easyfries25 said:Guys two questions on this paper were taken from the OCR board exam series.
