Примем вес груза большего плеча за Х, тогда вес груза меньшего плеча Х Н+160 Н.Учитывая,что большее плечо в 9 раз больше от меньшего и так как моменты равны,то получим уравнение:

9х=х+160

8х=160

х=20 Н(вес груза большего плеча), а х+160 или 20+160=180 Н(это вес меньшего плеча)

чтото типо этого такде сделай тол ко другие цифры и всё

mariannalferova: Спасибо❤️
