About This Quiz

How much do you know about levers from our classes? Take this quiz on levers and simple machines MCQ with answers to learn about simple machines. Most of the machines we use today have a lever or two, decreasing the force it would take to get a job done. A lever is a rigid body capable of rotating on a point itself. Play the quiz below and see if you understood all we covered on the topic and the application in real life.

  • 2. 

    A class 2 lever has the _____ in the middle.

    • Effort

    • Load

    • Fulcrum

    • All of these

    Correct Answer
    A. Load
    Explanation
    In a class 2 lever, the load is positioned in the middle. In this type of lever, the fulcrum is located at one end, while the effort is applied at the other end. The load is positioned between the fulcrum and the effort, making it the correct answer.

    Rate this question:

  • 3. 

    The unit used to measure the amount of force (effort) needed to lift a load is the:

    • Kilogram

    • Meter

    • Joule

    • Newton

    Correct Answer
    A. Newton
    Explanation
    The correct answer is Newton. Newton is the unit used to measure the amount of force or effort needed to lift a load. It is named after Sir Isaac Newton, a renowned physicist who formulated the laws of motion. The Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

    A class 3 lever has the _________ in the middle.

    • Effort

    • Load

    • Fulcrum

    • All of these

    Correct Answer
    A. Effort
    Explanation
    In a class 3 lever, the effort is located in the middle. In this type of lever, the fulcrum is at one end, the load is at the other end, and the effort is applied in between. The effort is the force applied to move the lever and overcome the resistance of the load. Since the question asks for the part that is located in the middle, the correct answer is "effort".

    Rate this question:

  • 5. 

    In a __________ Lever, the Force is between the Load and the Fulcrum.

    • Class Four

    • Class Three

    • Class Two

    • Class One

    Correct Answer
    A. Class Three
    Explanation
    In a Class Three Lever, the Force is between the Load and the Fulcrum. This means that the effort or force is applied on one end of the lever, the load is on the other end, and the fulcrum is located in between. This type of lever allows for increased force or power, as the force arm is longer than the load arm. Examples of Class Three Levers include tweezers, fishing rods, and human arms.

    Rate this question:

  • 6. 

    A benefit obtained by using a lever is called a(n)

    • Newton

    • Advantage

    • Interval

    • Effort

    Correct Answer
    A. Advantage
    Explanation
    A benefit obtained by using a lever is called an advantage because a lever allows for the amplification of force, making it easier to lift or move heavy objects. By using a lever, a smaller effort force can be applied over a longer distance to produce a larger output force over a shorter distance. This mechanical advantage provided by the lever allows for the accomplishment of tasks that would otherwise require much more effort.

    Rate this question:

  • 7. 

    Which of the following is NOT a component of a lever?

    • Fulcrum 

    • Effort 

    • Load 

    • Velocity

    Correct Answer
    A. Velocity
    Explanation
    The three essential components of a lever are:
    Fulcrum: The pivot point around which the lever rotates.
    Effort: The force applied to the lever to move the load.
    Load: The object being moved or lifted by the lever.
    Velocity is the speed and direction of an object's motion, which is not a defining component of a lever itself.

    Rate this question:

  • 8. 

    What is the relationship between the amount of effort required and its distance from the fulcrum?

    • The farther from the fulcrum the effort is, the more effort needed.

    • The farther from the fulcrum the effort is, the less effort needed.

    • The farther from the fulcrum the effort is, the equal effort needed.

    • All of the above

    Correct Answer
    A. The farther from the fulcrum the effort is, the less effort needed.
    Explanation
    The relationship between the amount of effort required and its distance from the fulcrum is that the farther from the fulcrum the effort is, the less effort is needed. This is because leverage increases as the distance from the fulcrum increases, allowing for a smaller amount of effort to produce a greater amount of force.

    Rate this question:

  • 9. 

    The farther from the fulcrum the effort is, the __________ is required to lift the load.

    • Less effort

    • More effort

    • Same effort

    • None of the above

    Correct Answer
    A. Less effort
    Explanation
    The farther away the effort is from the fulcrum, the less force is required to lift the load. This is because the longer lever arm created by the distance increases the mechanical advantage, allowing for the load to be lifted with less effort.

    Rate this question:

  • 10. 

    The human arm is a 

    • Class 2 lever

    • Class 3 lever

    • Class 4 lever

    • None of the above

    Correct Answer
    A. Class 3 lever
    Explanation
    A class 3 lever is characterized by having the effort force applied between the fulcrum and the resistance force. In the case of the human arm, the elbow joint acts as the fulcrum, the bicep muscle applies the effort force, and the weight or resistance being lifted or moved acts as the resistance force. This configuration allows for a greater range of motion and speed, but sacrifices the amount of force that can be exerted. Therefore, the human arm can be classified as a class 3 lever.

    Rate this question:

  • 11. 

    In ____________ levers, the effort increases as the load moves closer to the fulcrum.

    • Class 1

    • Class 2

    • Class 3

    • Class 4

    Correct Answer
    A. Class 3
    Explanation
    In class 3 levers, the effort is located between the load and the fulcrum. This configuration allows for a wider range of motion and increased speed of the load, but it requires greater effort to move the load as it gets closer to the fulcrum. Examples of class 3 levers include tweezers, fishing rods, and most sporting equipment like baseball bats and golf clubs.

    Rate this question:

  • 12. 

    A crowbar is a class _____ lever.

    • 1

    • 2

    • 3

    • 4

    Correct Answer
    A. 1
    Explanation
    A crowbar is a class 1 lever because the fulcrum is located between the effort and the load. In a class 1 lever, the effort is applied on one side of the fulcrum and the load is on the other side, with the fulcrum acting as the pivot point. In the case of a crowbar, the effort is applied at one end to pry or lift objects, while the load is the resistance or weight being lifted at the other end.

    Rate this question:

  • 13. 

    What kind of lever system is a hockey stick?

    • Class 1

    • Class 2

    • Class 3

    • A hockey stick is not a lever.

    Correct Answer
    A. Class 3
    Explanation
    A hockey stick is classified as a Class 3 lever system. In a Class 3 lever, the effort force is applied between the fulcrum and the load. In the case of a hockey stick, the fulcrum is the player's hands gripping the stick, the effort force is applied by the player's arms and hands, and the load is the puck being hit. This lever system allows for a greater speed and range of motion, making it ideal for shooting and passing in hockey.
