A Blank______-class lever has its components arranged as fulcrum-weight-force.Multiple choice question.secondthirdfirst

Step 1: Break Down the Problem

To determine which class of lever has its components arranged as fulcrum-weight-force, we need to understand the definitions of the three classes of levers.

Step 2: Relevant Concepts

1. First-Class Lever: The fulcrum is between the effort (force) and the load (weight). Example: See-saw.
2. Second-Class Lever: The load (weight) is between the fulcrum and the effort (force). Example: Wheelbarrow.
3. Third-Class Lever: The effort (force) is between the fulcrum and the load (weight). Example: Tweezers.

Step 3: Analysis and Detail

From the arrangements:

• Fulcrum - Weight - Force means the load (weight) is located between the fulcrum and the applied force (effort). This specifically describes a second-class lever.

Step 4: Verify and Summarize

In a second-class lever, the configuration indeed follows the stated arrangement: the fulcrum at one end, the load in the middle, and the applied force on the opposite end.

Final Answer

The correct answer is second.
