Find the next number: 3, 7, 15, 31, ___?
Answer: 63
Each term follows the rule ×2 + 1, so 31 × 2 + 1 = 63.
Which instrument is used to verify that an elevator car sill is level?
Answer: Spirit level
A spirit level with a bubble vial is used to confirm the car sill is perfectly horizontal.
A hoist rope stretches 0.125 inch under load. Express this as a fraction in lowest terms.
Answer: 1/8 inch
0.125 = 125/1000 = 1/8 in lowest terms.
What is the purpose of summarizing a text in Elevator Industry Aptitude Test assessment?
Answer: To demonstrate understanding by condensing key points into a brief overview
Summarizing demonstrates comprehension by requiring the reader to identify and articulate the most important points of a text in a concise format, showing they understand the essential content.
Which type of thread provides the greatest mechanical advantage for converting rotary motion to linear motion, commonly used in elevator screw-drive systems?
Answer: Acme thread
Acme threads have a trapezoidal profile that provides high efficiency and load-bearing capacity for power transmission applications like screw-drive elevators.
A load test weight of 907.2 kg is needed. Approximately how many pounds is that? (1 kg ≈ 2.205 lbs)
Answer: 2,000 lbs
907.2 kg × 2.205 lbs/kg ≈ 2,000 lbs.
A staircase rises 8 inches per step and has a horizontal run of 10 inches per step. What is the total height of a 5-step staircase above the floor?
Answer: 40 inches
Total height equals the rise per step multiplied by the number of steps: 8 × 5 = 40 inches.
What type of sentence is this: 'Inspect the cables before every shift.'?
Answer: Imperative
Imperative sentences give commands or instructions and often omit the subject 'you.'
Which tractor has to drive farther in order to bring the boat to shore?
Answer: 2
Explanation: Tractor 2 will drive in a straight horizontal heading, in the same direction as the boat is from the shore. This is the shortest line possible. Tractor 1 will also drive in a horizontal line, but as it is tied to the boat diagonally it will therefore pull the boat over a larger distance. However, tractor 1 will have to apply less force due to the mechanical help from the rock (the same as in a movable pulley).
A 1,000 kg elevator car is at rest. What is the tension in the supporting rope? (g = 9.8 m/s²)
Answer: 9,800 N
At rest (no acceleration), tension equals weight = 1,000 × 9.8 = 9,800 N.
A tension spring stretches 3.175 cm under load. What is this measurement in millimeters?
Answer: 31.75 mm
3.175 cm × 10 mm/cm = 31.75 mm.
A passage from a technical specification states: 'All wiring shall be run in conduit, except low-voltage signal wiring, which may be run in cable trays or raceways.' A 24V control signal wire would most appropriately be installed in:
Answer: A cable tray or raceway
At 24V, the wire qualifies as low-voltage signal wiring, which the specification explicitly permits to be run in cable trays or raceways.
A solid steel shaft will resist twisting (torsion) better than a hollow shaft of the same outer diameter because:
Answer: The statement is false — a hollow shaft with the same outer diameter often resists torsion nearly as well per unit weight
A hollow shaft of equal outer diameter has nearly the same torsional rigidity as a solid one because material near the center contributes little to torsional resistance.
A safety manual states: 'All personnel must wear hard hats in areas where overhead work is being performed.' A mechanic is working in the machine room above the elevator shaft. Which employees below MUST wear hard hats?
Answer: Any employee in the elevator shaft below
The rule applies to areas where overhead work is being performed, so anyone in the shaft below the mechanic must wear a hard hat.
An elevator safety gear grips the guide rails to stop the car. The stopping force is an example of:
Answer: Friction force
Safety gear clamps the rail and uses friction to decelerate and stop the car.
FAHRENHEIT is to ________ as POUND is to WEIGHT.
Answer: Temperature
Explanation: The analogy "FAHRENHEIT is to TEMPERATURE as POUND is to WEIGHT" indicates a relationship between units of measurement. Fahrenheit is a unit of temperature, while pound is a unit of weight.
Choose the word that best completes the analogy: Brake is to stop as cable is to ___.
Answer: suspend
A brake functions to stop movement; a cable functions to suspend the elevator car.
A wire rope makes two full wraps around a sheave. How many degrees of total rotation does this represent?
Answer: 720 degrees
One full wrap equals 360 degrees, so two full wraps equal 720 degrees.
Which sentence uses 'fewer' and 'less' correctly?
Answer: Fewer complaints were filed after the upgrade.
'Fewer' applies to countable nouns like 'complaints,' while 'less' applies to uncountable quantities.
A safety bulletin reads: 'Personnel must wear hard hats, safety glasses, and steel-toed boots in the machine room at all times.' Which item is NOT required by the bulletin?
Answer: Hearing protection
The bulletin lists hard hats, safety glasses, and steel-toed boots; hearing protection is not mentioned.
