In a bottle opener, the fulcrum is:
At the end
In the middle
There is no fulcrum
Near to the effort point
A bottle opener is a second class lever. In a bottle opener, the fulcrum is at the end. Point 2 is the load point and point 1 is the effort point.
State the class of levers and the relative positions of load (L), effort (E) and fulcrum (F) in (a) a bottle opener, and (b) sugar tongs.
The type of lever in which effort is in the middle between the fulcrum and the load
The lever for which the mechanical advantage is less than 1 has the :
(a) fulcrum at the midpoint between the load and effort.
(b) load between the effort and fulcrum.
(c) the effort between the fulcrum and load.
(d) load and effort acting at the same point.
