Does aluminum block beta radiation?
Why? You just rent steel dead menThey are on a truck and they delievr it to your jobThey have certfied weightsCheers and good luck!
CertainlyBeta radiation is just electronsAnd electrons are just what electricity is all aboutAnd aluminum conducts electricitySo obviously it blocks it.
Friction would be negligibleJust use the weight of the concrete itself, or better, lift a tank of waterYou will want to be able to measure the weight with a considerable amount of precision, and water is able to be calculated with high precisionAlternatively, anchor a steel strap in the ground, place a strain guage on the strap (or several strain guages) and pull with the craneRead the strain in the steel, and back-calculate the stress (force that caused the displacement)Using the cross sectional area of the steel, and the material properties, you should be able to get a fairly close estimate of the force applied to the steel by the crane.
