While researching a topic, a student has taken the following notes:
●A lever is a simple machine consisting of a rigid beam and a fulcrum.
●The fulcrum is the point about which the beam pivots.
●The input force (effort) is the force applied to the lever.
●The output force (load) is the force that the lever exerts on another object.
●In first-class levers, the fulcrum is located between the effort and the load.
●In second-class levers, the load is located between the effort and the fulcrum.
The student wants to contrast first-class levers and second-class levers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
