Question

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)
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)
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 = 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 choice is the third list:

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)

(Reason: class 1 has the fulcrum between effort and load; class 2 has the load between fulcrum and effort; class 3 has the effort between fulcrum and load.)
