This lever, constructed from wood or a lightweight metal alloy, measures at least 500 mm in length and includes an axis for tripod mounting along with balancers at both ends. It features a centered scale starting at 0 and holes positioned at equal intervals from the center to each end. This tool is designed to demonstrate weight principles, lever equilibrium, and the addition of parallel forces. It is also used for verifying the rule of moments, showing the equality of work, and determining equilibrium conditions for bodies acted upon by multiple forces.
