Start your Module 11 torsional vibration recap

This quiz is designed to reinforce difficult MCA oral knowledge on crankshaft and shaft-line torsional vibration, critical speeds, dampers, detuners, barred speed ranges and survey/class evidence.

Define torsional vibration, natural frequency, resonance, nodes and antinodes.
Explain critical speeds and why barred speed ranges must be passed quickly.
Differentiate viscous dampers, spring dampers, detuners and flexible couplings.
Identify symptoms such as gear chatter, fretting, damper heat and fatigue cracking.
Apply Chief Engineer fault response for misfire, damper defects and BSR passage issues.
Connect TVA, class approval, trials, measurements and modification control.
About this module

This module forms part of the TST Engineering Services E-Learning Recap Area. It supports structured MCA Engineering Oral Examination preparation by reinforcing torsional vibration theory, practical fault recognition, machinery protection and oral-exam answer structure. It does not replace tuition or mock oral practice; it is intended to strengthen revision, recall and weak-area identification.
