  1. A centrifugal pump delivers reduced flow despite correct motor speed. Which condition is LEAST likely to be the cause?

    Answer: Oversized suction pipe diameter

    An oversized suction pipe actually improves flow by reducing velocity and friction losses; it would not cause reduced pump output.

  2. What is the purpose of a regenerative drive (drive with regenerative braking) on a production machine?

    Answer: To return braking energy back to the power supply rather than dissipating it as heat

    A regenerative drive converts the kinetic energy during deceleration back into electrical energy and returns it to the supply grid, improving energy efficiency.

  3. A technician is troubleshooting an intermittent fault on a machine. Which approach is most effective for capturing the fault?

    Answer: Install a data logger or use PLC data capture to record conditions at the time of fault

    Data logging captures the exact conditions—inputs, outputs, temperatures, speeds—at the moment an intermittent fault occurs, providing the evidence needed for diagnosis.

  4. Which maintenance document records all work performed on a specific machine, including parts replaced and labor hours?

    Answer: Equipment maintenance history log

    An equipment maintenance history log tracks all maintenance activities performed on a machine over its life, supporting trend analysis and reliability improvement.

  5. A pneumatic system loses air pressure overnight when the compressor is off and no tools are connected. The BEST method to locate the leak is:

    Answer: Apply soapy water or use an ultrasonic leak detector along joints and fittings

    Soapy water or an ultrasonic detector identifies exact leak locations by detecting escaping air at fittings, valves, and hose connections.

  6. When performing a laser alignment on a coupled shaft, a technician finds both angular and parallel misalignment. In what order should corrections typically be made?

    Answer: Correct parallel first, then angular

    Correcting parallel (offset) misalignment first simplifies the subsequent angular correction, as angular adjustments can reintroduce offset if done first.

  7. A cutting tool on a CNC lathe produces a rough surface finish and chatters at the end of a cut. The MOST likely mechanical cause is:

    Answer: Worn spindle bearings causing radial play

    Worn spindle bearings allow radial movement of the spindle under cutting forces, causing chatter and poor surface finish especially at the end of the cut.
