THREE CLASSES OF LEVER There are three classes of lever and each class has fulcrum, load and effort which together can move a heavy weight. CLASS 1 The workman uses a trolley to move the large packing case. The fulcrum is the wheel. CLASS 2The gardener uses a wheel barrow to lift tools and garden waste. The load is in the centre of the barrow CLASS 3 The fisherman catches the fish which becomes the load at the end of the lever.

∙ 12y agoLevers are one of the basic tools that were probably used in prehistoric times. Levers were first described about 260 BC by the ancient Greek mathematician Archimedes (287-212 BC). A lever is a simple machine that makes work easier for use; it involves moving a load around a pivot using a force. Many of our basic tools use levers, including scissors (2 class 1 levers), pliers (2 class 1 levers), hammer claws (a single class 2 lever), nut crackers (2 class 2 levers), and tongs (2 class 3 levers). It all depends on where the fulcrum point is as compared to the load point.

What is the relationship between distance ratio and mechanical advantage?
The mechanical advantage of a lever is the ratio of the length of the lever on the applied force side of the fulcrum to the length of the lever on the resistance force side of the fulcrum. There are three types of levers - class 1, class 2, and class 3.
What are 5 facts about levers?
#1.- A lever is a machine. #2.- A lever consists of a rigid rod or beam pivoted at a fixed hinge, or fulcrum. #3.- Based on the location of the fulcrum, the load, and the effort, the lever is divide into three types. #4.- A lever is one of the six simple machines identified by Renaissance scientists. #5.- A lever provides the mechanical advantage known as leverage.
