Thermal expansion of bronze question.

[Oscarpop]

I'm not up to this, so for my own curiosity can someone do some physics problem for me.

Bronze cylinder ( the nut on my prop).

If it is an average composition bronze and I heat it from zero degrees to say 150 degrees .

If its internal diameter at zero degrees is 30mm, what will it be at 150 degrees.

( fully aware that the s/s shaft will also heat up and expand at a lower rate )

Many thanks

See Kaye and Laby 2.3.5 http://www.kayelaby.npl.co.uk/general_physics/2_3/2_3_5.html

It will expand by 0.078 mm to 30.078mm


The stainless shaft by 0.063mm
