Question
In first-class lever the load is located at some point between the effort and the fulcrum.Question 7Answera.Trueb.False
Solution
The statement is False. Here's a step-by-step explanation:
-
A lever is a simple machine that consists of a bar that pivots at a fixed point, known as the fulcrum.
-
There are three classes of levers, and they are classified based on the relative positions of the load, effort, and fulcrum.
-
In a first-class lever, the fulcrum is located between the effort and the load. An example of a first-class lever is a seesaw.
-
In a second-class lever, the load is located between the effort and the fulcrum. An example of a second-class lever is a wheelbarrow.
-
In a third-class lever, the effort is located between the load and the fulcrum. An example of a third-class lever is a pair of tweezers.
So, the answer is b. False.

While researching a topic, a student has taken thefollowing notes:• A lever is a simple machine consisting of a rigidbeam and a fulcrum.• The fulcrum is the point about which the beampivots.• The input force (effort) is the force applied to thelever.• The output force (load) is the force that the leverexerts on another object.• In first-class levers, the fulcrum is located betweenthe effort and the load.• In second-class levers, the load is located betweenthe effort and the fulcrum.The student wants to contrast first-class levers andsecond-class levers. Which choice most effectivelyuses relevant information from the notes toaccomplish this goal?A) In levers, the effort is the force applied to thelever; the load, in contrast, is the force that thelever exerts on another object.B) In first-class and second-class levers, the fulcrumand the load are in different locations.C) First-class levers are simple machines consistingof a rigid beam and a fulcrum, but then again,the same is true of second-class levers.D) In first-class levers, the fulcrum is locatedbetween the effort and the load, but insecond-class levers, the load is located betweenthe effort and the fulcrum.
