Final answer:
A First-Class Lever is a type of lever where the fulcrum is in between the effort and the load. An example is a seesaw. When drawing, the fulcrum is in the middle with the effort and load on either side.
Step-by-step explanation:
A First-Class Lever is a type of lever where the fulcrum is located between the effort (or force) and the load. It has three parts: the fulcrum, the effort, and the load. An example of a first-class lever is a seesaw at a playground.
To draw and label a first-class lever, you create a straight line (that's your lever or board). Mark a point in the middle - this is your fulcrum. At one end, mark an 'E' - this is where the effort is applied. At the other end, mark an 'L' - that's where the load is. The 'E' and 'L' can be switched depending on the specific situation, but the fulcrum is always in the middle.
