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 closer the bat's balance point is to the handle, the easier it is to swing. I have two bats in my lab which I routinely bring into my physics classroom to illustrate this point to my students. One bat is aluminum and the other is composite, but bats are 34-inches long and both weight exactly 30-oz.
