n.a
reference to a connecting rod, a slender
bar of metal that transmits
power from the engine of a
steam locomotive to its wheels.
Steam locomotives
burn fuel so that water can be heated to
create steam, which is then used to push a piston back and forth. The piston is connected to the wheels via a rod which serves to
transfer the
energy of the
burning fuel and
steam into
motion of the locomotive wheels.
