The seesaw is a long lever arm with the load at one end, the effort at the opposite end, and the fulcrum in the center. With both the second and third class levers, however, the fulcrum is at one end of the lever and both the load and effort are on one side of the fulcrum. The seesaw is closest in arrangement to a first class lever because it is the only class of lever with the fulcrum between the load and effort.

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group.

Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
