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

Respuesta :

The list that correctly orders effort (E), fulcrum(F) and load (L) for each lever class is

  • 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).

Machine are instruments that make work easier, faster, and convenient to do,

The lever is an example of the machine and we have 3 classes of lever depending on the position of the Load, Effort, and Fulcrum.

Three types of lever are;

  • First-class lever - The fulcrum (F) is between the Load and the effort
  • Second class lever: The load (L)is between the effort (E) and the fulcrum(F).
  • Third class lever: The effort (E) is between the load (L) and the fulcrum (F)
