  • 2. 

    A more common name for and inclined plane is...

    • A ramp

    • A side lift

    • A tail gate

    • A board

    Correct Answer
    A. A ramp
    Explanation
    An inclined plane is commonly referred to as a ramp because it is a flat surface that is inclined at an angle, allowing objects to be moved up or down with less force than if they were lifted vertically. A ramp is often used to make it easier to move heavy objects, such as pushing a cart up a ramp instead of lifting it straight up.

    What is a simple machine?

    • A system made up of subsytems.

    • Many machines made up to make one machine.

    • A curved piece of glass.

    • A tool or device made up of one basic machine.

    Correct Answer
    A. A tool or device made up of one basic machine.
    Explanation
    The correct answer is "A tool or device made up of one basic machine." This explanation is supported by the fact that a simple machine refers to a single mechanical device that can change the direction or magnitude of a force, such as a lever, pulley, or inclined plane. It is not a system made up of subsystems or multiple machines, nor is it a curved piece of glass.

    Which 2 things does a pulley consist of?

    • 2 wheels/circles

    • 1 wheel and 1 rope/wire/belt

    • 1 rope and 1 belt

    • 1 circle/cylinder and 1 wheel

    Correct Answer
    A. 1 wheel and 1 rope/wire/belt
    Explanation
    A pulley consists of one wheel and one rope/wire/belt. The wheel is designed to rotate freely around an axle, and the rope/wire/belt is wrapped around the wheel. When force is applied to one end of the rope/wire/belt, it causes the wheel to turn, allowing for the transmission of force and motion. The combination of the wheel and the rope/wire/belt is what enables the pulley to function and perform tasks such as lifting heavy objects or changing the direction of a force.

    A wedge can be used to hold things together and...

    • Catapolt things

    • Move things

    • Split things apart

    • Crush stuff

    Correct Answer
    A. Split things apart
    Explanation
    A wedge is a simple machine with a triangular shape that is used to separate or split objects apart. When a wedge is inserted into a narrow space and force is applied to it, the wide end of the wedge pushes against the objects, causing them to separate or split apart. This makes the answer "Split things apart" the correct choice. A wedge is not typically used to catapult things, move things, or crush stuff.

    A lever consists of 3 main parts...which 3?

    • Axel, fulcrum and effort

    • Fulcrum, load and stick

    • Effort, fulcrum and load

    • Side, fulcrum and bar

    Correct Answer
    A. Effort, fulcrum and load
    Explanation
    A lever is a simple machine that consists of three main parts: the effort, the fulcrum, and the load. The effort is the force applied to the lever, the fulcrum is the pivot point or support on which the lever rotates, and the load is the object being moved or lifted. These three components work together to create mechanical advantage and allow for the amplification of force or the ability to lift heavy objects with less effort.

    Inclined planes make work easier but they do create more_____then lifting.

    • Friction

    • Fear

    • Weight

    • Steepness

    Correct Answer
    A. Friction
    Explanation
    Inclined planes make work easier because they reduce the amount of force needed to move an object vertically. However, they do create more friction compared to lifting the object directly. Friction is the resistance encountered when two objects move against each other, and in the case of inclined planes, the object slides or rolls against the surface of the plane, causing more friction than lifting it straight up.

    The inclined plane looks alot like which other simple machine?

    • Pulley

    • Wheel an axel

    • Screw

    • Wedge

    Correct Answer
    A. Wedge
    Explanation
    The inclined plane resembles a wedge because both have a sloping surface that allows for easier movement or separation of objects. A wedge is essentially a double-sided inclined plane, where the thick end can be used to push or split objects apart. Similarly, an inclined plane is a flat surface set at an angle, which reduces the effort required to lift or move objects. Therefore, the inclined plane and the wedge share similar characteristics and can be considered as similar simple machines.

    Which of these are the definition of a third class lever?

    • Has the fulcrum between the load and effort

    • Has the effort between the load and fulcrum

    • Has the load between the effort and fulcrum

    • There is no third class lever

    Correct Answer
    A. Has the effort between the load and fulcrum
    Explanation
    A third class lever is defined as having the effort between the load and fulcrum. In this type of lever, the effort is applied closer to the fulcrum than the load. This means that a smaller effort is required to move a larger load, but the load will move over a shorter distance than the effort. Third class levers are commonly found in human anatomy, such as when using a pair of tweezers or when flexing the bicep muscle.

    Which of the following is an example of a Simple Machine.

    • A staircase

    • A door stopper

    • A water jug

    • A coffee can

    Correct Answer
    A. A door stopper
    Explanation
    A door stopper is an example of a simple machine because it allows for the transfer of force to hold a door in place. By placing the door stopper on the ground and pushing the door against it, the door stopper creates a lever that prevents the door from closing. This lever action makes it easier to keep the door open without exerting a lot of force.
