...Archimede suggested,in a simple manner,the first step,a "fifty per cent" design of a gravity machine.He,before anybody,proved the motion of a lever and more...Let's read again,his Assumption 1:"Equal weights,at equal distances from the fulcrum,balance(*).Equal weights,at unequal distances from the fulcrum,do not balance,but the weight at the greater distance will tilt its end of the lever ,down"(**).So,about the lever,we have,in a concise shape,(*)=a static problem of a weighting machine,and (**)=an obsevation about dynamics,that can be a suggestion for a tilt,topple,overturn of this one.It helps us,to imagine in the most facile manner,the picturing of the first stroke of a possible gravity machine.This can be the first step.Who make the next?All the Bests!/Alex
