Weight of Spoke Train Wheel

[Anonymous]

I am looking to recover an old three spoked train wheel from the ocean and I would like to know the approximate weight.

It is about 3' to 4' in diameter and the spokes curve within the wheel.

Thanks,

John

Well let's see. Iron is roughly 1200# per cubic foot so a 3' diameter wheel would have a radius of 1.5' . Volume = pi x r squared x height. So if it was solid it would be 1.5x1.5x3.1416x .25 x 1200 = roughly 2000# but it isn't solid so if you can figure what percentage is solid say roughly 30% it should weigh around 600#, 20%=400#, 40% = 800# so I would guess 600# or less.
