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.
B. Class 2 Levers. The class 2 lever has the fulcrum at one end, the force at the other end, and the load in the middle. A common example is the wheelbarrow, where the wheel is the fulcrum, the load rests within the box, and the force is the lift supplied by the user.A class 2 lever always has a mechanical advantage of greater than 1.he class 1 lever has the fulcrum between the force and the load, as in a seesaw. When two people of equal weight use the seesaw, they position themselves an equal distance from the fulcrum, and the system is balanced.
