The lever for which mechanical advantage is less than 1 has:
- Fulcrum at the mid-point between load and effort.
- Load between effort and fulcrum.
- Effort between fulcrum and load.
- Load and effort acting at the same point.

Answer
Effort between fulcrum and load.
Reason — In class III lever, i.e., when effort is between fulcrum and load the mechanical advantage is less than 1.
