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?
In levers, the effort is the force applied to the lever; the load, in contrast, is the force that the lever exerts on another object.
A
In first-class and second-class levers, the fulcrum and the load are in different locations.
B
First-class levers are simple machines consisting of a rigid beam and a fulcrum, but then again, the same is true of second-class levers.
C
In first-class levers, the fulcrum is located between the effort and the load, but in second-class levers, the load is located between the effort and the fulcrum.
D
