Question from Jerry, a parent:

I am trying to weigh a large possibly 1000 lb cylinder on a 500 lb scale, is this possible? If so what is the actual formula to figure out the correct weight? I am told it is possible with the fulcrum method but have not been able to find a formula. Thanks Jerry


If you have a long beam able to support the cylinder you can support the beam at one end, put the scale at the other, and put the cylinder in between;


The weight of the cylinder is D2/D1 (W - B/2) where W is the weight shown on the scale and B the weight of the beam.

However, it may be preferable to search out the right equipment
