Question

Which list correctly orders effort (E), fulcrum (F), and
load (L) for each lever class?
class 1 = L, F, E (or E, F, L)
class 2 = F, L, E (or E, L, F)
class 3 = F, E, L (or L, E, F)
class 1 = F, L, E (or E, L, F)
class 2 = F, E, L (or L, E, F)
class 3 = L, F, E (or E, F, L)
class 1 = F, E, L (or L, E, F)
class 2 = L, F, E (or E, F, L)
class 3 = F, L, E (or E, L, F)
class 1 = F, E, L (or L, E, F)
class 2 = F, L, E (or E, L, F)
class 3 = L, F, E (or E, F, L)

Answer 1

Here's the correct order of effort (E), fulcrum (F), and load (L) for each class of lever:

- **Class 1 Lever**: Fulcrum (F) is in the middle, with Load (L) on one side and Effort (E) on the other.
- Order: **F, L, E** (or **E, L, F**)

- **Class 2 Lever**: Load (L) is in the middle, with Fulcrum (F) on one end and Effort (E) on the other.
- Order: **F, E, L** (or **L, E, F**)

- **Class 3 Lever**: Effort (E) is in the middle, with Load (L) on one end and Fulcrum (F) on the other.
- Order: **L, F, E** (or **E, F, L**)

So in summary:

- Class 1: **F, L, E** (or **E, L, F**)
- Class 2: **F, E, L** (or **L, E, F**)
- Class 3: **L, F, E** (or **E, F, L**)

Make sure to double-check the combinations as there are various interpretations, but the foundational rules above apply.
