Using a longer handle while keeping the force and its perpendicular distance unchanged
Applying the same force in the opposite rotational direction at the same perpendicular distance
Applying the same force at the same point but reducing its perpendicular distance
Applying a larger force while keeping its perpendicular distance unchanged
