The most recognizable type of lever is the first-class variety. A well-known application features a pivot point situated in the middle, with the applied force exerted at one end and the load at the opposite end. As seen on the diagram to your left, you can easily shift an imposing weight using just a light amount of effort. First-class levers resemble teeter-totters or seesaws. Effort is applied and resisted in equal yet opposite measures. The fulcrum - that key pivot point - splits the two forces evenly apart. Everyday tools such as crowbars, scissors and others often incorporate this fundamental mechanism into their operation. Other types of levers are also put to good use by man-made instruments designed for moving weight with minimum labor exertion; third-class levers are another well-documented case in point. Baseball bats, oars, and various forms of hand-held shovels come to mind when considering examples from the field of human activity and endeavor that involve shifting loads around without undue difficulty using first-class mechanisms or lever setups for maximum efficiency purposes always taken into consideration naturally when such instruments are employed by mankind overall throughout this world we live in currently today!
