Fill in the correct form of the word in capital letters

An engineer on board can identify something ERROR in equipment by feeling the heat. More movement means more CRITICAL of the object condition. Vibration analysts measure velocity data for a specified time period and carry out analysis ACCORDING . Machine failures can be drastically reduced by adopting a PREVENT Maintenance Tool program. Whenever machine vibration crosses normal limits it indicates some problem in the mechanism, which could involve ALIGN , wear and tear or LOOSE of parts. To overcome this CORRECT actions should be undertaken based on collected data from the machine. When vibrations occur in big sized machines, operating under heavy loads, the INTENSE of vibration magnifies because of large mass rotation and COMBUSTION gases forced inside the machinery. If the vibration levels increase beyond the minimal level, it may lead to DEFORM or BREAK of engine components. There are two basic criteria for determining ACCEPT in the level of vibrations. TORSION Dampers address twisting vibrations from EVEN torque pulses. Dampers absorb vibration energy to reduce OSCILLATE frequency. BALANCE in rotating components is one of the common reasons for engine vibrations. HARMONY resonance is one of the reasons for engine vibration. Silicon is a VISCOSITY fluid. The FOUL of the propeller is one of the reasons for engine vibration. AXIS dampers help reduce vibration.
