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.
An example of a first-class lever is a seesaw. There are not many first-class levers in the body. One example is the head resting on the vertebral column. When the head is raised, the facial portion of the skull is the resistance. The joint between the atlas and occipital bone (Atlanto-occipital joint) is the fulcrum.
