The question i need help on is question 6 part (c). I think I need to use the equation:
2. Equations used:
[tex]\Delta[/tex]L = [tex]\alpha[/tex]L[tex]\Delta[/tex]T
Linear expansion of steel: 12x10 K^-1 ([tex]\alpha[/tex])
Density of steel: 7800
3. My attempted solution:
I tried substituting in the values into the equation but the question did not mention anything about the length of the steel so now i am stuck for a solution. I tried using proportionality with density=mass/volume so density is proportional to 1/L. However im not sure this if this is the correct way.
Thanks for your help in advance.
