Discovered law of pulley and lever
WebStudents are introduced to three of the six simple machines used by many engineers: lever, pulley, and wheel-and-axle. In general, engineers use the lever to magnify the force applied to an object, the pulley to lift heavy loads over a vertical path, and the wheel-and-axle to magnify the torque applied to an object. The mechanical advantage of these machines … Web• invented the sciences of mechanics and hydrostatics. • discovered the laws of levers and pulleys, which allow us to move heavy objects using small forces. • invented one of the most fundamental concepts of physics …
