Sample MMO ASAN Elevator Engineering Practice Questions

Try these sample questions to review concepts for the MMO ASAN Elevator Engineering exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 20+ question experience with AI tutoring.

1During röleve alma, opposing shaft walls intrude 25 mm and 15 mm into a nominal 1800 mm depth at different heights. Their positions share one survey datum. What depth remains for an unobstructed vertical installation prism?

A.1785 mm

B.1800 mm

C.1760 mm

D.1775 mm

Explanation: A plumb prism must clear both wall envelopes throughout the shaft height. Its depth is 1800-25-15 = 1760 mm, even though the intrusions occur at different levels.

2In a simplified direct-acting hydraulic lift, the ram supports 2800 kg including payload and ram mass. Its effective pressure area is π(120 mm)²/4. Neglecting friction, what static cylinder pressure results with g = 9.81 m/s²?

A.2.43 MPa

B.1.21 MPa

C.4.86 MPa

D.0.243 MPa

Explanation: The supported force is 2800 × 9.81 = 27,468 N and the effective area is 11,310 mm². Pressure is 27,468/11,310 = 2.43 N/mm² = 2.43 MPa.

3An overspeed governor detects excessive car speed and initiates safety-gear operation. Which component then applies the arresting mechanical action directly to the guide rails?

A.The landing-door interlock

B.The car safety gear

C.The governor tensioning weight alone

D.The pit buffer before the car reaches it

Explanation: Safety gear engages the rails to arrest and support the car. The governor detects overspeed and initiates the action, while buffers act only when contacted at a terminal end.

4A lift-component calculation cites a superseded adopted standard edition and leaves its load-case assumptions undocumented. What is the appropriate technical review?

A.Accept it if the steel grade has not changed

B.Check only whether the final safety factor is greater than one

C.Accept the old worksheet if a similar lift used it previously

D.Verify the applicable current requirements and reproduce the required checks from documented assumptions

Explanation: Lift component methods must be applied with the applicable adopted safety requirements and defined load cases. An old worksheet or an isolated safety-factor result does not demonstrate that the current project's required checks were completed.

5A guide-rail section experiences bending moment 900,000 N·mm about an axis with section modulus 18,000 mm³. Using σ = M/W, what is bending stress?

A.50 MPa

B.25 MPa

C.100 MPa

D.500 MPa

Explanation: Stress is 900,000/18,000 = 50 N/mm², equivalent to 50 MPa. The moment and section modulus must refer to the same bending axis.

6A rail has effective buckling length 2500 mm and radii of gyration 28.5 and 19.0 mm. Using λ = Lk/imin, what slenderness controls?

A.87.7

B.105.3

C.131.6

D.19.0

Explanation: The smaller radius of gyration is 19.0 mm. Slenderness is therefore 2500/19.0 = 131.6 for the weaker buckling axis.

7For an ideal elastic column model of a rail, E = 206,000 MPa and λ = 131.6. Using σE = π²E/λ², what is the Euler critical stress?

A.58.7 MPa

B.117.4 MPa

C.206.0 MPa

D.234.8 MPa

Explanation: The calculation is π² × 206,000/131.6² ≈ 117.4 MPa. This ideal elastic result is not a substitute for the full prescribed rail buckling and combined-stress checks.

8In a rail deflection model δ = 0.70FL³/(48EI), all quantities except bracket spacing stay constant. If spacing increases from 2.0 to 2.5 m, by what factor does deflection increase?

A.1.25

B.1.563

C.2.441

D.1.953

Explanation: Deflection scales with the cube of the unsupported span in this model. Thus the ratio is (2.5/2.0)³ = 1.953, an increase of about 95%.

9A rail deflects 4.08 mm at bracket spacing 2000 mm. The project's deflection limit is 3.50 mm. Assuming δ scales as L³ and other parameters stay fixed, which is the largest listed spacing that passes?

A.1900 mm

B.1800 mm

C.2000 mm

D.2100 mm

Explanation: At 1900 mm, δ = 4.08(1900/2000)³ = 3.498 mm, just below the specified limit. The 2000 and 2100 mm spans fail, while 1800 mm passes but is not the largest passing option.

10For a conservative biaxial rail check, use σm = Mx/Wx + My/Wy. Given Mx = 900,000 N·mm, My = 600,000 N·mm, Wx = 18,000 mm³, and Wy = 12,000 mm³, what is σm?

A.50 MPa

B.70.7 MPa

C.100 MPa

D.75 MPa

Explanation: Each bending term is 50 MPa. Their specified additive combination is 100 MPa; a detailed section analysis can be needed when extreme stresses occur at different profile points.

About the MMO ASAN Elevator Engineering Exam

Independent practice for ASAN elevator engineering, distinct from ASAA preliminary-project and periodic-inspection qualifications. Study the published theory topics and the three assessed calculation areas.

Exam sponsor: TMMOB Makina Mühendisleri Odası (MMO) / Personel Belgelendirme Kuruluşu (PBK). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Written assessment: 30 minutes for theory and 150 minutes for project calculations. Theory covers survey methods, standards, lift equipment and shaft/machine-room matters (5 points each); projects cover rail strength (40), suspension ropes (20) and traction (20). Pass: 70/100. No separate oral or hands-on component is described on the scheme page.

Time Limit

2Distinguish rope strength, fatigue and traction checks.

3Label project assumptions and use current adopted standards and manufacturer data.

Frequently Asked Questions

Who is eligible?

PBK's published scheme lists mechanical engineering and at least 18 hours of training, with the preliminary elevator-project qualification required for certification. Ask MMO whether current degree-route extensions apply to your qualification and sitting; the older scheme wording alone does not establish an exhaustive 2026 exclusion.

What are the official assessment languages?

The reviewed scheme and current-year listings do not establish permitted response languages. Confirm with PBK; this English study bank does not establish an official English examination.

How should these questions be used?

Use the worked MCQs to check methods, then complete full written rail, rope and traction projects with the required drawings, tables and applicable current standards.
