. Explain Lever and its types with examples.
Answers
Answer:
Three different types of levers exist, depending on where the input force, fulcrum, and load are. A class 1 lever has the fulcrum between the input force and load. A class 2 lever has the load between the fulcrum and input force. A class 3 lever is a lever that has the input force in between the fulcrum and the load.
Explanation:
There are three types or classes of levers, according to where the load and effort are located with respect to the fulcrum. Class 1 has the fulcrum placed between the effort and load, Class 2 has the load in-between the effort and the fulcrum, and Class 3 has the effort between the load and the fulcrum.
Other examples of first class levers include a crow bar and rowboat oars. A Class 2 lever has the load between the fulcrum and the input force. A classic example is a wheelbarrow, where the wheel acts as the fulcrum, whatever's in the bucket part is the load, and where your hands pull up is the input force.
