A candidate applying to write a Power Engineer certificate of competency examination must:
A. Undergo mandatory drug testing
B. Hold the next lower class of qualification
C. Pass a criminal records check
D. Pass both written and oral examinations
Correct Answer: B
Rationale:
Progression requires holding the previous certification level as a prerequisite.
A machine lifts a 12 kN load with 4 kN effort over 8 m at 70% efficiency. Load distance is:
A. 0.54 m
B. 3.81 m
C. 1.87 m
D. 0.38 m
Correct Answer: C
Rationale:
Efficiency affects mechanical advantage; solving energy balance gives 1.87 m.
The Mechanical Refrigeration Code is:
