Ive to work out the uncertainties for youngs modulus.

would i take all 4 measurements and mutliply then divide by 4 ?

would 1.788m have an uncertain if +/- 0.01 ?

how would i get the uncertainties from 5.73x10-3

im very confused and my tutor isn't helpful at all.

basically my stress and strain are

A = 5.73 x 10-3
L = 1.788m
F = 8.829 kg m s-1
e = 6.36cm or 6.36x10-1m

youngs modulus is 6.02x10(10) Pa
ive to find the % uncertainty in the Young Modulus value
