(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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)

2. Relevant equations

Diameter of wire: 0.31mm (therefore area is 0.302mm²)

Length of wire: 2m70cm (270cm)

3. 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
