Homework Statement
I had to do an experiment and create a graph with the data.
We attached one end of the Iron wire to a clamp and then tied on weights of 100g at a time to the other end so that a force can be applied to the Iron wire and so it stretches. (as pizza1512 did but in copper)
Homework Equations
Diameter of wire: 0.31mm (therefore area is 0.302mm²)
Length of wire: 2m70cm (270cm)
The Attempt at a Solution
i worked out that if u apply 100g (1Newton force)
1/2700= 3.7x10^-4 (not sure if right)
And stress is
1/0.302= 3.3
I worked out the Youngs Modulus
3.3/(3.7x10^-4) and i got 8918.92
is that right?
and how do i plot it on a graph
