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, 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 = 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 = 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, 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 = 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)
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

The correct order of effort (E), fulcrum (F), and load (L) for each class of lever is as follows:

• Class 1 lever: Fulcrum (F) is in the middle, with effort (E) on one side and load (L) on the other. So, it's F, E, L or L, E, F.
• Class 2 lever: Load (L) is in the middle, with effort (E) on one side and fulcrum (F) on the other. So, it's F, L, E or E, L, F.
• Class 3 lever: Effort (E) is in the middle, with load (L) on one side and fulcrum (F) on the other. So, it's L, F, E or E, F, L.

Given these descriptions, the correct answer is:

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)

So, the first option matches this combination correctly.
