Homework Statement
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 can't figure it out...can someone take these results and make them so there right and give me there method ><
Homework 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 going to be miles off?
