Engines like the one shown in this picture were
used for many purposes. They used steam created by heating water
to move mechanical arms back
and forth. The back and forth motion would spin big wheels.
The motion could be harnessed to power many different
devices. Engines could generate electricity, lift heavy objects
for construction, or turn giant drills for mining.
