  1. Two gears mesh together. If the driver gear has 10 teeth and the driven gear has 30 teeth, how does the driven gear turn compared to the driver?

    Answer: Three times slower

    A larger driven gear with more teeth turns proportionally slower, here three times slower than the smaller driver.

  2. When two gears mesh directly, how do their rotation directions compare?

    Answer: They rotate in opposite directions

    Directly meshed gears always rotate in opposite directions.

  3. A first-class lever is most clearly represented by which everyday tool?

    Answer: A pair of scissors

    Scissors are a first-class lever with the fulcrum (pivot) between the effort and the load.

  4. Moving the fulcrum closer to the load on a lever has what effect on the effort needed to lift it?

    Answer: Decreases the effort needed

    Placing the fulcrum nearer the load lengthens the effort arm, reducing the force required.

  5. In a fixed pulley system (single fixed pulley), what is the main advantage to the user?

    Answer: It changes the direction of the applied force

    A single fixed pulley only changes the direction of the force, not its magnitude.

  6. Which liquid property allows hydraulic systems to transmit force effectively?

    Answer: Liquids are nearly incompressible

    Hydraulics work because liquids are nearly incompressible, so pressure transmits force throughout the system.

  7. If a bolt is tightened with a right-hand thread, which direction do you turn it to loosen it?

    Answer: Counterclockwise

    Standard right-hand threads loosen counterclockwise, following the 'lefty-loosey' rule.
