MECHANICS EXAM REVIEW-NEIEP
QUESTIONS AND ANSWERS | 2026
UPDATE | 100% CORRECT.
A contractor wants to raise the car speed from 100 fpm to 125 fpm, it currently has a 12"
sheave. What is required? - ANS 100 fpm/125 fpm= 12"/ X =15
A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage or resistance.
What should you do? - ANS Replace it with a larger MOV - 630
On a Ward-Leonard circuit the brake is set, but the motor is trying to slip through the brake.
What is the issue? - ANS Suicide Circuit - 425
You have an old DC motor and are adding an SCR drive, what do you do to the interpoles? -
ANS Leave the interpoles alone. When adding a SCR drive to the generator, the series loop is
removed, as are the 3 resistors. Everything else remains the same
A hydro runs up with no load but will not run with a full load. What is the issue? - ANS The
relief valve is set too low - 815
Runby for a 1:1 hits the CWT buffer 4" below the top landing. CWT runby should be set at 18".
How much should the ropes be shortened? - ANS 22" - 235
You need to work on a freight door retiring cam, you LOTO the main line but there is still power
on the cam. What circuit is still hot? - ANS Door Operator disconnect -535

,The contractor requests that the vertical center of a Rack and Pinion hoist be moved. How do
you do this? - ANS Adjust tie downs and wall ties - 850
Working pressure on a Hydro is 400 PSI. What is the maximum relief valve setting? - ANS 400
x 150%= 600 PSI - 815
What must be installed on a false care before operation? - ANS Spring Loaded safeties - 110
There is slight arcing between the brush and commutator. What action must be taken? -
ANS None
Note: Heavy arcing= light brush pressure, Heavy brush pressure= mechanical wear
If rigging is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb load. What is the beam
capacity? - ANS 18,000lbs -210
How much resistance is measured over a normally closed switch? - ANS .2 Ohms- should be
zero but will never be that low
A car traveling in the hoistway always stops at the same spot and blows a fuse. What causes
this? - ANS traveling cable has a cut/exposed wire or a short - 515
How is a class 1 yearly buffer test preformed? - ANS Car at the bottom landing and on
inspection, jump out direction and final limits. With pit clear, run down to compress the buffers,
buffers should fully extend within 90 seconds.
Note: 5 yr is Full load, full speed - 555
How many strain supports are required on a 350 ft raceway? - ANS 4
1 every 100ft - 505-510
How is stainless steel drilled out? - ANS Slow speed and constant pressure - 205

, What is the required amout of retainer clips for wedge shackles and what is the spacing? -
ANS At least 2. First clip being 4 times the diameter of the rope from the top of the shackle,
and the second clip is 8 times the diameter of the rope away from the shackle. - 245
A 300 ohm resistor burns out, but you dont have another one. How can you make one? -
ANS 2- 600 ohms resistors in parallel is 300 ohms. Resistance is half of the highest resistor in
the parallel circuit. 3- 225 ohms is 75 ohms. - 345
When cutting laminated panels, which direction should the finish side face? - ANS Finish side
facing the cutting edge of the tool. Blade will burr the backside. - 225
How do you cut a finished floor? - ANS Cutting blade away from the finished side - 255
A 480 VAC stepdown 240 VAC transformer is connected to a 3 phase rectifier, what is the output
voltage? - ANS 320 VAC
3 phase full wave= 1.33 x output voltage. - 715
A car is loaded with 125% and sinks, why? - ANS Slipping through the brake
IF you find a broken or missing barricade what should you do? - ANS Write up a formal
inspection request
What are the consequences of misaligned joints on a rack and pinion? - ANS Broken gear
teeth. CWT derailment. Excessive wear/crease the surface of the tube. - 850
A dumbwaiter is 9 sqft in area, 4 ft in height, and capacity is 13.9lb/ft. What is the total
capacity? - ANS 9 X 4 x 13.9= 500lbs Max Capacity
