Match each of the following common mechanical tools to the correct description of its lever configuration.
- A pair of pliers gripping a boltThe fulcrum is located between the effort and the load (First-class lever).
- A nutcracker breaking a shellThe load is located between the fulcrum and the effort (Second-class lever).
- A pair of tongs lifting a block of iceThe effort is located between the fulcrum and the load (Third-class lever).
Cevap
Pliers are matched to a first-class lever (fulcrum in the middle). The nutcracker is matched to a second-class lever (load in the middle). The tongs are matched to a third-class lever (effort in the middle).
Each tool physically represents a specific lever class based on the arrangement of the fulcrum (pivot), the effort (input force), and the load (output resistance). By tracing the pivot point, where the user applies force, and where the work is done, each tool accurately maps directly to a specific lever configuration.
