Wedge Splits Wood by Jack Patterson

Wedge Splits Wood explores the surprising depth behind a seemingly simple tool: the axe. It examines how the mechanics of a wedge, a basic principle of applied physics, have shaped human history and continue to influence modern technology.

Delving into the history of axes reveals how their designs evolved over millennia, impacting fields from shipbuilding to forestry.

The book highlights how a small input force, when properly applied through a wedge, can generate a much larger output, enabling the splitting of tough materials like wood.

The book approaches its subject through a multidisciplinary lens, bridging history, mechanical engineering, and anthropology.

It begins with the physics of wedges, moves to the historical evolution of the axe from the Stone Age to modern times, and then examines the cultural significance of wood splitting in various societies.

It reveals the cultural impact of axes, noting how wood splitting has shaped rituals and traditions across different societies.

The book culminates by discussing modern applications of wedge mechanics in areas like construction and medicine.
