hey

my youngs modulus for all my results for c.w has come out "blehege"

Y=youngs modulus

F=force

A= area 5.255x10-8

X=extension

L= original length 1m make things quicker

my Y for when F=1.5 and X=0.05x10-3 i get a stress of 26198585 my stress is 2000 which makes my Y=5.2x10to the 10

and later on when my F=11 and X=10x10-3 my stress is 192122958 and stress 100 which makes Y= 1.9x10 to the 10

ive done something really wrong here but i cant figure it out......can someone take these results and make them so there right and give me there method ><

2. Relevant equations

i used

Stress = force divided by area

strain = extension divided by original length

Youngs modulus= stress divided by strain

on my results page of my c/w my teacher wrote that it should be a constant which makes sense so i think i worked something out wrong? or is it just my equipment was so bad its gonna be miles off?
