Question

You have an aluminum housing that calls for two holes 12 inches apart. The drawing notes that this

dimension applies at 68 degrees F. The manufacturing plant is 93 degrees F. The machine you are using

is steel, so it grows as well, and it was certified at 68 degrees F.

1) How long must you make the hole spacing in the aluminum part so that it will be correct at 68

degrees?

2) How long do you need to tell the steel machine to go to reach the correct hole spacing above?

(what length will grow to the dimension you answered above)

3) Name a metal that can be melted on your kitchen stove
