Tutors cover undergraduate vibrations syllabi.
| Area | Topics |
|---|---|
| Fundamentals | Simple harmonic motion, degrees of freedom, energy methods |
| Free vibration | Undamped and damped single-DOF systems, Rayleigh's method |
| Forced vibration | Harmonic excitation, base excitation, rotating unbalance |

A machine of mass 5 kg sits on a spring of stiffness 20,000 N/m with a damping coefficient of 100 N·s/m.
| Step | Working | Result |
|---|---|---|
| Natural frequency | ωn = √(k ÷ m) = √(20,000 ÷ 5) | ≈ 63.2 rad/s (≈ 10.1 Hz) |
| Critical damping | cc = 2√(km) = 2√(100,000) | ≈ 632.5 N·s/m |
| Damping ratio | ζ = c ÷ cc = 100 ÷ 632.5 | ≈ 0.158 (underdamped) |
| Damped natural frequency | ωd = ωn√(1 − ζ²) | ≈ 62.5 rad/s |
Using the same system (ζ ≈ 0.158).
| Question | Working | Answer |
|---|---|---|
| Magnification factor at frequency ratio r = 0.8 | 1 ÷ √((1 − 0.64)² + (2 × 0.158 × 0.8)²) | ≈ 2.27 |
| Transmissibility at r = 2 | √(1 + 0.632²) ÷ √((1 − 4)² + 0.632²) | ≈ 0.39 |
| Condition for isolation | Transmissibility < 1 | r > √2 ≈ 1.41 |
At r = 2, only about 39% of the force reaches the foundation; adding more damping above r = √2 actually increases transmitted force.
Tutors match your level, syllabus and exam board, from school to PhD.

Most lost marks come from mixing rad/s and Hz and misreading response curves.
| Mark-loser | What to do instead |
|---|---|
| Mixing rad/s and Hz | f = ω ÷ 2π; state which you use |
| Wrong critical damping formula | cc = 2√(km) = 2mωn |
| Damping always reduces transmitted force | Above r = √2, more damping increases transmissibility |
| Ignoring phase | Report phase angles where asked |
| Mode shapes not normalised | Normalise as your course requires |
| No free-body diagram | Draw the FBD before writing equations |
Mechanical vibrations is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Problem sets | Accurate derivations and calculations |
| Exams | Single- and multi-DOF problems |
| Lab reports | Measured frequencies and damping compared with theory |
| Design tasks | Isolator or absorber design |
| Simulation work | MATLAB or FEA modal analysis |
Vibration engineers use these tools.
| Tool | What it is used for |
|---|---|
| MATLAB or Python | Solving equations and plotting responses |
| Accelerometers and data acquisition | Measuring vibration |
| FFT analysers | Frequency analysis |
| ANSYS or Abaqus modal analysis | Natural frequencies of complex structures |
| Shakers and impact hammers | Modal testing |
Mechanical vibrations is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where mechanical vibrations is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | BEng mechanical and aerospace engineering | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Mechanical vibrations courses | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Mechanical engineering degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Mechanical engineering programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | B.Tech/BE mechanical engineering dynamics of machinery and vibrations, and GATE | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of mechanical vibrations help depends on the type of task and your deadline. A short problem costs less than a full design task. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Yes. Tutors explain theory and work through problems and lab reports, within your university's rules.
The frequency at which a system vibrates freely after being disturbed: ωn = √(k ÷ m).
The ratio of actual damping to critical damping, ζ = c ÷ cc.
The smallest damping that returns a system to rest without oscillating.
Underdamped systems oscillate as they decay; overdamped systems return slowly without oscillating.
The natural log of the ratio of successive amplitudes, used to estimate damping.
When forcing frequency nears natural frequency, amplitudes grow large and can cause fatigue failure or damage.
