Abstract
<p>The transportation of monoliths by ancient civilizations has long been a subject of speculation, with limited materials and technology posing constraints on available methods. This study revisits this intriguing debate by examining the properties of four-bar mechanisms, type-two levers, and the physical limitations of laborers. In particular, we explore the feasibility of a device proposed by Boles and Morris, leveraging the principles of Second Class levers. This proposed device optimally positions the pivot against the ground, utilizing friction between the support timber and the ground as a stable pivot point. A rope, attached to the furthest point of the timber, transfers the operator's force to the lever's effort position, influencing the load's position and exerting force on the monolith. Notably, this system offers the advantage of requiring the operator's effort only during the initial half of the movement, with gravity facilitating the latter half of the monolith's descent back to the ground.</p>
