Cyrtomium falcatum. 1  Aptly named, Japanese holly fern produces fronds that do indeed resemble holly leaves with their glossy, deep green leathery appearance. 2  It needs moist but well-drained soil in a protected location to thrive. 3  It also makes for a good houseplant in climates where it isn't hardy.
A baseball bat is a third-class lever because the fulcrum is on the  end of one side, the effect force is in the middle, and the  resistant force, the load, is at the top.
There are three classes of lever 1st, 2nd and 3rd class. First class levers have the fulcrum between the force and the load. In using a screwdriver to lift the lid from a paint tin you are moving the effort over a greater distance than the load.
