history review 25

simple machines: without simple machines there is no gears and no gears is no tv no car no games no phones. other simple machines like the waterwheel the waterwheel is important for moving water from lake to lake. the crank is in a tv to switch channels and in trains the crank had to be used by men it is now fully auto matic simple machines are used every single day without it we riding horses and no tv. sometimes people do use horses though so it is even from modern to old. but something from old is still around a long time ago around 500bc people made a job a miner people still mine for ore like iron gold diamonds and gems this was to sell for money and get rich it was luck tough.
