Sections covered on the exam: Graphic Problem Solving, Interpreting Diagrams, The Mechanical Concepts Test, Reasoning From Rules.
Question 1 · Graphic Problem Solving
(25 Questions = 6-7 questions per topic from the 4 subtopics below)
Explanation: In technical illustrations and schematics, a zigzag line is the standard symbol used to represent a resistor. Recognizing common symbols is critical for interpreting engineering drawings.
Answer: B. Ground
A triangle with a line underneath is a conventional symbol used to denote ground in electrical diagrams.
Question 2 · Graphic Problem Solving
Answer: D. Linear
As resistance increases, voltage drop increases at a constant rate — a linear relationship.
Question 3 · Interpreting Diagrams
Answer: C. By label linked to the coil
Relays are labeled to match their associated coil, ensuring clarity when tracing control paths.
Question 4 · The Mechanical Concepts Test
Explanation: Known as the law of inertia, this describes how objects remain at rest or in motion unless a force is applied.
Answer: A. Newton
The Newton (N) is the standard unit of force in the metric system.
Question 5 · Reasoning From Rules
If Rule: “If valve A is open, then motor B must be off.”
Answer: A. Rule is violated
The conditional rule states: A open → B off. If B is on, the rule is broken.
Question 6 · Reasoning From Rules
If the system is in Mode A, valves 2 and 3 stay open.
Answer: D. Valves 2 and 3 open
Direct deduction from stated mode condition.
Question 7 · Graphic Problem Solving
Answer: C. 1:5
Slope = Rise/Run = 4/20 = 1:5
Question 8 · Interpreting Diagrams
Answer: B. Conditioned space
Supply air is delivered to the conditioned area for climate control.
Question 9 · The Mechanical Concepts Test
Answer: A. Fixed
A fixed pulley changes the direction of force but not the amount needed.
Question 10 · The Mechanical Concepts Test
Answer: B. Tensioner
A tensioner keeps the belt taut, ensuring smooth operation.
