NEIEP MECHANICS PRACTICE PAPER 2026
QUESTIONS WITH SOLUTIONS GRADED A+
●● Who is responsible for providing the MSDS on a construction site?
Answer: Your employer.
●● If a pump pulley is 6" and the motor pulley is 12", how do you
determine the size pulley needed to achieve a speed of 125' per minute?
Answer: Cross multiply based on the pulley sizes and motor speed.
●● In a dump switch question, if the switches are in certain states, how
do you determine the car's position? Answer: Find the switch in the
neutral position; the answer is believed to be the second floor.
●● How many gallons of oil are needed to raise a car with a 6" diameter
piston and a 25' rise? Answer: It would take 37 gallons of oil.
●● How do you convert 1 inch to millimeters? Answer: 1 inch is equal
to 25.4 mm.
●● What is the correct method to measure a handrail? Answer: Measure
in flat sections on the incline only.
,●● When is an escape hatch required for residential lifts? Answer: When
there are no controls inside the car and it must open to the outside.
●● How many wires are needed to wire a COP? Answer: You need 10%
extra wires, considering multiple common terminals.
●● What could be the cause if a brake doesn't pick fully upon
acceleration? Answer: It could be related to the brake circuit.
●● What is the formula for calculating the time constant of a capacitor?
Answer: TC = RxC, and capacitors take 5 times to charge.
●● What issue arises if doors open and close immediately? Answer: It
indicates a problem with the off delay circuit.
●● What should you ask for when installing rails? Answer: Fish plates.
●● When is the first tie down required for 2'x8' scaffolding? Answer: At
4 times the smallest base diameter, find the closest header above.
●● What hole should you drill first when dropping in machine beams?
Answer: Drill the deflector sheave hole first.
, ●● At what speeds do mechanical and electrical trips occur for cars
running at 300-350 fpm? Answer: For 300 fpm, mechanical trip at 395
and electrical at 355; for 350 fpm, mechanical trip at 454 and electrical
at 407.
●● What types of safeties should be equipped for cars running at 300
fpm? Answer: Type A safeties (no more than 150 fpm) and Type B
wedge clamp.
●● What is an acceptable way to test oil buffers? Answer: Test for 90
seconds at high speed/inspection speed.
●● If a car is at the bottom normally, which way will it not run? Answer:
The car will not run down; it will run up.
●● How do you test safeties annually? Answer: Conduct a low speed no
load Category one elevator test.
●● What is the proper method for drilling into stainless steel doors?
Answer: Use eye protection, drill slowly and steadily with a sharp bit
and cutting oil.
●● What is the method for drilling into sand? Answer: Use a rotary drill.
