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.
The load is the resistance of the wood. With the human forearm, the fulcrum is the elbow, the biceps muscle supplies the effort, and the load is the wood's resistance. In addition to third-class levers, there are first- and second-class levers. One example of a first-class lever is a seesaw. An example of a second-class lever is a wheelbarrow.
