Why is the mechanical advantage of a lever of the third class always less than one? Give one example of this class of lever.

Explanation

### Step-by-Step Solution:

1. **Understanding Lever Types**:
- A lever is a simple machine that consists of a rigid bar that rotates around a fixed point called the fulcrum. There are three classes of levers based on the relative positions of the effort, load, and fulcrum.

2. **Identifying Third Class Lever**:
- In a third class lever, the effort is applied between the fulcrum and the load. This means that the load is further away from the fulcrum than the point where the effort is applied.
