Second class lever has

Question

Accepted Answer

The correct option is (3):
Resistance is in between fulcrum and force
The three classes of levers are differentiated by the relative positions of the Fulcrum (F), the Resistance or Load (R), and the Effort or Force (E). A Second-Class Lever is specifically identified by the arrangement where the **Resistance (R)** is located between the **Fulcrum (F)** and the **Effort (E)**. A simple way to remember this is the order R-F-E is impossible, so the resistance (R) must be in the middle of the other two points. Since the effort (E) is always farther from the fulcrum than the resistance (R) in this arrangement, the effort arm is longer than the resistance arm, guaranteeing that the lever is a force multiplier, giving it a mechanical advantage greater than one. Common examples include a wheelbarrow or a nutcracker.

The incorrect option is (1):
Fulcrum is in between force and resistance
This statement describes the arrangement of a **First-Class Lever**. In this class, the **Fulcrum (F)** is situated between the Effort and the Resistance. A seesaw, a pair of scissors, or a crowbar used to pry something up are all examples of a first-class lever.

The incorrect option is (2):
Force is in between fulcrum and resistance
This statement accurately defines a **Third-Class Lever**. In this configuration, the **Effort (E)** or force is applied at a point between the Fulcrum and the Resistance. The human forearm acting to lift a weight (with the elbow as the fulcrum and the bicep muscle insertion as the effort) is the most common anatomical example, as this class is built for speed and distance of movement rather than force multiplication.

The incorrect option is (4):
It is without fulcrum
This option is incorrect because the fulcrum is the fundamental, defining element of a lever. A lever is essentially a rigid bar or beam that pivots around a fixed point; this fixed point is precisely the **fulcrum**. Without a fulcrum, the system cannot rotate or pivot, and thus it cannot be classified as a lever of any class.
