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.
â¢ Output force (also called the load) - the force applied by the lever to move the load. There are three types of levers: first class, second class and third class. The difference between the three classes depends on where the force is, where the fulcrum is and where the load is.In a first class lever, the fulcrum is located between the input force and output force.evers in the Human Body Page 2 The three classes of levers can be found in your body. Use diagrams A, B, and C to answer the questions below. Also label the effort (input force), fulcrum, and load (output force) on each diagram. 15. _____________________ LEVER C 19.
