I think it will make use of tables...

The Attempt at a Solution



Can someone tell me the solution step by step of this problem? Help me please :(
Thanks in advance..

I'd like to help but the wording of the question is poor and additional data needed to solve problem would have to be looked up .

There are in any case potentially four different answers depending on the four combinations possible for high/low on the two diameter tolerances .

use desmos (or similar) and plot the equations for thermal expansion

plot two lines

the expansion of steel
the expansion of copper

You will then be able to read off the temperatures easily

or you could put the relevant dimensions into the equation to begin with - whatever you are happy with
 
Thanks for all the answers :)
