  1. A worm gear driving a spur gear is commonly used because it provides:

    Answer: A large gear reduction and high torque

    Worm gears give a large speed reduction and high torque, often with a self-locking feature.

  2. In an electrical circuit, increasing the resistance while voltage stays constant will cause the current to:

    Answer: Decrease

    By Ohm's law, higher resistance at constant voltage results in lower current.

  3. Which arrangement of two springs supporting a load gives the LEAST total stretch?

    Answer: Two springs in parallel (side by side)

    Springs in parallel share the load and stiffen the system, giving the least stretch.

  4. A wheel and axle works as a force multiplier when force is applied to the:

    Answer: Large wheel to turn the small axle

    Applying force to the large wheel to turn the smaller axle multiplies the output force.

  5. Cooling a sealed container of gas while keeping its volume fixed will cause the gas pressure to:

    Answer: Decrease

    At fixed volume, lowering temperature reduces gas pressure, per Gay-Lussac's law.

  6. Which bearing type is best suited to handle a heavy thrust (axial) load along a shaft?

    Answer: Thrust bearing

    A thrust bearing is specifically designed to support axial loads along the shaft direction.

  7. A cam in a rotating mechanism is used primarily to:

    Answer: Convert rotary motion into reciprocating (back-and-forth) motion

    A cam converts rotary motion into a precise reciprocating or linear motion of a follower.
