Put one's shoulder to the wheel

Origin

The phrase paints a vivid picture straight from a bygone era, long before engines and paved roads. Imagine a heavy cart, laden with goods, stuck deep in the mud of a rural track. The horse strains, but the wheel refuses to budge. What's needed? Human brawn. Someone, or several people, would physically lean into the wheel, bracing themselves and pushing with all their might, using their shoulder as a fulcrum to apply maximum force. This literal act of getting something moving through sheer manual effort, often in cooperation with others, morphed into the figurative sense we use today. By the 19th century, this powerful image had already cemented itself in the English lexicon, symbolizing the determined application of one's energy to a collective, difficult task.
