answer is c
highlighted answer is wrong its option B
P between F and W
The answer is option C. Google it. 3rd order is effort between load and fulcrum
The correct answer is that effort should be between Fulcrum and Load.
in lever of 3rd class, effort is in middle means effort P is in middle which is option C.
c is correct option
Effort is in the middle in the lever of third order
P between w and f
