Sample Pancyprian Machine Elements T.S. (Practical) Practice Questions

Try these sample questions to review concepts for the Pancyprian Machine Elements T.S. (Practical) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A single rivet of diameter d = 10 mm is loaded in pure shear by F = 12 kN. Average shear stress is:
A.76.4 MPa
B.152.8 MPa
C.38.2 MPa
D.191.0 MPa
Explanation: A = πd²/4 = 78.54 mm². τ = 12000/78.54 = 152.8 MPa.
2An M12 bolt has tensile stress area ≈ 84.3 mm². With σ_all = 160 MPa, maximum axial tensile load is closest to:
A.8.5 kN
B.13.5 kN
C.19.2 kN
D.27.0 kN
Explanation: F = 160 × 84.3 = 13488 N ≈ 13.5 kN. Choose the option that matches this evaluated result and reject values from misapplied formulas.
3An M10 bolt is tightened with T = 40 N·m. Using T = 0.2·F·d (d = 10 mm), estimated preload F is:
A.10 kN
B.20 kN
C.40 kN
D.80 kN
Explanation: F = T/(0.2d) = 40/(0.2×0.010) = 20000 N = 20 kN.
4One rivet d = 12 mm in double shear; τ_all = 90 MPa. Allowable load based on rivet shear is closest to:
A.10.2 kN
B.20.4 kN
C.30.6 kN
D.40.8 kN
Explanation: A = 2·(π·12²/4) = 226.2 mm². F = 90×226.2 ≈ 20.4 kN.
5Bolt core diameter d_c = 8.376 mm carries 15 kN tension. Tensile stress is closest to:
A.136 MPa
B.204 MPa
C.272 MPa
D.340 MPa
Explanation: A = π·8.376²/4 ≈ 55.1 mm². σ = 15000/55.1 ≈ 272 MPa.
6For M16×2, pitch diameter d₂ = d − 0.6495·P. With d = 16 mm and P = 2 mm, d₂ is:
A.14.70 mm
B.15.35 mm
C.14.35 mm
D.13.70 mm
Explanation: d₂ = 16 − 0.6495×2 = 14.701 mm ≈ 14.70 mm.
7Rivet bearing: d = 16 mm, t = 8 mm, σ_b,all = 180 MPa. Allowable load for one rivet is:
A.11.5 kN
B.18.4 kN
C.23.0 kN
D.36.2 kN
Explanation: A_b = d·t = 128 mm². F = 180×128 = 23.0 kN.
8Compared with a riveted permanent joint, a screw (bolt) connection is:
A.Always stronger than an equal-diameter rivet
B.A detachable (removable) connection
C.Unable to carry tensile loads
D.Made by melting the parent metal
Explanation: Screw connections are detachable (λυόμενες); rivets form permanent joints.

A.71 MPa
B.142 MPa
C.213 MPa
D.284 MPa
Explanation: 12 kN per bolt. σ = 12000/84.3 ≈ 142 MPa.
10M20×2.5 thread: how many full turns advance a nut 15 mm?
A.4 turns
B.5 turns
C.6 turns
D.7.5 turns
Explanation: Advance per turn = pitch 2.5 mm. Turns = 15/2.5 = 6.

About the Pancyprian Machine Elements T.S. (Practical) Exam

Machine Elements (Στοιχεία Μηχανών, code 513) is the practical-direction Technical School access subject covering mechanical connections, shafts, bearings, couplings, gear/belt/chain power transmission, mechanisms, seals and lubricants. The written paper rewards correct formula selection and unit handling on sizing and ratio problems. This bank provides 100 original English-language MCQs with worked calculations and per-option explanations mapped to those syllabus areas.

Exam sponsor: Examinations Service, Cyprus Ministry of Education, Sport and Youth. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

The official assessment is a single 2.5-hour written paper in Greek on the Technical School practical-direction Machine Elements syllabus, combining theory and comprehension with structured numerical exercises on connections, shafts, bearings, couplings and gear/belt/chain drives. This 100-question bank is an English-language MCQ study adaptation, not an official translation or format simulation.

Time Limit

2 hours 30 minutes per the official 2026 Pancyprian Access Examinations timetable and code 513 syllabus

Passing Score

Marked on a 0-20 scale; no pass mark - feeds the access/ranking grade (βαθμός πρόσβασης) for Cyprus and Greece public university allocation.

Exam / Certification Fees

EUR 25.00 per access subject for 2026 (EUR 50.00 only for Practical Physical Performance Test code 032), payable electronically by card during the official 2–17 April 2026 payment window per Examinations Service notices.

Pancyprian Machine Elements T.S. (Practical): Suggested Study Strategy

1Master the core machine-element formulas: τ = 16T/(πd³), σ = 32M/(πd³), T = 9550·P/n, i = n1/n2 = z2/z1 = d2/d1, d = m·z, a = m(z1+z2)/2, L10 = (C/P)^p, v = πdn/60000.
2Always convert millimetres to metres before applying stress formulas that use SI units (N, m, Pa).
3For gear and chain drives, write the speed ratio both ways (teeth and rpm) and check that the product of driven teeth and driven rpm equals driver teeth times driver rpm.
4For bearings, identify ball (p = 3) vs roller (p = 10/3) before using the life equation, and convert life between revolutions and hours with L10h = 10⁶/(60n)·(C/P)^p.
5Practise writing full Greek solutions: given data, formula, substitution, result with units — exactly as the written paper demands.
6Review connection theory (rivet layouts, thread forms, key types, weld symbols) in your own words — Cyprus papers weight conceptual understanding as well as arithmetic.

Frequently Asked Questions

Is this practice bank the same as the official Pancyprian Machine Elements paper?

No. The official exam is a 2.5-hour written paper in Greek with constructed-response theory and structured calculation exercises. This bank is an English-language MCQ study adaptation: use it to drill formulas and concepts, but practise full written solutions with units separately, because the real paper requires you to produce them yourself.

Who sits Machine Elements code 513?

It is the Machine Elements access subject for candidates from Cyprus Technical and Vocational Schools of Education and Training on the practical direction (Π.Κ.). The 2026 paper was scheduled for Friday 19 June 2026, 08:00–10:30, per the official timetable.

What topics does the code 513 syllabus cover?

Connections (rivets, press fits, screw fasteners), keyed and elastic connections, welding, axles/shafts/journals, bearings and couplings, gear drives, belt drives, chain drives, mechanisms, sealing means and lubricants, with repeated emphasis on worked numerical exercises for stresses, ratios, speeds and sizing.

How is the paper marked and is there a pass mark?

The paper is marked on a 0-20 scale. There is no pass or fail threshold: the mark feeds the candidate's access/ranking grade (βαθμός πρόσβασης) used for admission to public universities in Cyprus and Greece.

Are calculators allowed?

Exam regulations on permitted materials are set by the Examinations Service and published in the official Guide and exam-day instructions; check panexams.moec.gov.cy for the current rules rather than relying on third-party summaries.

How should I use this bank most effectively?

Work topic by topic alongside your school textbook: attempt each calculation with pen and paper, check units (mm vs m, rpm vs rad/s), and re-derive every numeric answer. Then attempt past official papers from the Examinations Service under timed, written conditions.
