Принцип работы такой: с некоей силой F1 мы давим на маленькую площадь, под ней образуется давление, которое давит на большую площадь и за счёт этого даёт большую силу на выходе. Давление есть отнощение силы к площади: P=F/S Раз у нас цилиндр, его сечение круговое и площадь сечения равна: S=П*R^2 = П*(D/2)^2 = П * D^2 / 4 Отнощение площадей будет: S1 / S2 = (П * D1^2 / 4) / (П * D2^2 / 4) = D1^2 / D2^2 = 50*50 / 4*4 = 2500 / 16 = 156,25 Давление силы F1 в большом цилиндре будет равно давлению в малом цилиндре с силой F2: P = F1/S1 = F2/S2 Отсюда F1/F2 = S1/S2 = 156,25 раз
