mathmatician needed

I have plenty on hand, and checking the weights of materials, it is about 4.7X the weight of concrete. Lead weighs 708 pounds per cubic ft. vs. 150 pounds for concrete. This makes the lead a far better choice for maximum weight density.

So, if the weight diameter is 18", how thick would it have to be made, to weigh 500 pounds? Remember, lead weighs 708 pounds per cubic foot. Thanks.

If you want to go with the lead, consider how you"re going to handle 500# weights. Maybe go with two or three thinner disks that you can stack in place.

Lead weights 708 lbs per cubic foot or .409 lbs per cubic inch. And the area of a circle is Pie(3.1417) times radius squared-then 3.14 times 9 squared is 254.47 square inches therefore if it is 1 in thick it would weigh 254.47 times .409 which equals 104.078 lbs.Then 500 lbs divided by 104.078 equals 4.80 inches thick.

First, being from Kentucky, we weren't taught such mathematics in the 5th grade. And besides that, it has been many years since I eventually was taught the theory of pi. Therefore when challenged, I am not too proud to publicly admit my ignorance and seek the help of those more learned, than I.

As for the environment and lead..... lead is a naturally occurring mineral within the upper strata of the Earth's crust. I would guess it has been present for at least a few billion years, if not longer. It is actually a rather innocuous substance unless heated to the point of vaporization (900+ degrees F) or rendered into dust and then inhaled.

Obviously, iron/steel wheel weights are superior structurally and if money wasn't an issue for me, I'd just lay out about $500 for a thousand pounds of used rear weights and be done with it.

Concerning how the weights would be formed/molded, yes, they would be poured about one inch thick and stacked.

My tractor has flanged axles, so no center hole is needed. The weights would just have to be removed in order to unbolt the wheel in case of a flat tire, etc.

Thanks again.
