Question

What type of lever has the load resistance between the fulcrum and the force?

• A. First class lever
• B. Second class lever
• C. Both (A) and (B)
• D. Third class lever

Hint:

The classification of levers and their mechanical advantages are determined by the positioning of the fulcrum, load, and applied force.

Answer 1

The Correct Option is B

To solve the problem, we need to identify the type of leverload (resistance) lies between the fulcrumeffort (force).

Answer:
This type of lever is a Second-Class Lever.

Explanation:

• In a second-class lever, the fulcrum is at one end, the effort is applied at the other end, and the load is positioned in between.
• This arrangement provides a mechanical advantage, allowing a small force to move a larger load.
• Example in real life: A wheelbarrow.
• Example in the human body: Standing on tiptoes (toes act as fulcrum, body weight is the load, and calf muscles provide the effort).

Final Answer:
A Second-Class Lever has the load (resistance) between the fulcrum and the force.
