Machines Every Where

My dear friends this a first for me i have never done this before so bare with me machines are every where no matter where we go there they are we cant get away from them even the Romans used them and the Greeks we know the Greeks even dabbled with steam power on a small scale many did not realize its potential so it didn't get very far the people of the fareast were using gun powder in wepons long be fore we in the west did a machine can beas simple as a long wooden shaft used to say move small boulders any thing to give you an advantage over just muscle power even an Iron crow bar or a long handle shovel i was watching a video on youtube last night on vintage power plants from 2000 hp radial air plane engine to a monster 30 ton Desile engine used to produce power in Holland i think that will be all for now this is my first time so be kind i promise i will read your comments many thanks everyone.
