NAVY AVIATION MACHINIST EXAMS SCRIPT QUESTIONS
AND ANSWERS 2025/2026 ALL RATED A+
✔✔Newtons Laws of Motion - ✔✔Law of interia
Law of Force and Acceleration
Law of Interaction
✔✔Law of Interia - ✔✔Newtons first Law
States a mass at rest will stay at rest while a mass in motion will stay in motion until
acted upon by an outside force.
✔✔Law of force and acceleration - ✔✔Newtons Second Law
When a body is acted upon by a constant force the acceleration is inversely proportional
to it's mass
F=ma
✔✔Law of Interaction - ✔✔Newtons 3rd Law
For every action there is an equal and opposite reaction
✔✔Heat - ✔✔Form of energy produced by motion of molecules known as kinetic energy
British thermal unit
Calorie
✔✔Methods of heat transfer - ✔✔conduction, convection, radiation
✔✔Conduction - ✔✔transfer of heat from molecule to molecule
✔✔Convection - ✔✔transfer of heat by means of currents in a fluid caused by uneven
heating (boiling water)
✔✔Radiation - ✔✔Transfer of heat by means of high speed particles of energy
✔✔Temperature - ✔✔Intensity of hotness/coldness of a mass measured in degrees.
✔✔Atmosphere - ✔✔Known as the whole mass of air surrounding the earth. 78% N,
21% O, and 1% Inert gas
✔✔Layers of the atmosphere - ✔✔troposphere, stratosphere, mesosphere,
thermosphere
✔✔Trophosphere - ✔✔Lower level of the atmosphere containing weather
✔✔Stratosphere - ✔✔Second level that has an avg. temperature of -69.7 degrees F
and is the best conditions for flying due to dense air.
, ✔✔Mesosphere - ✔✔Third Level that has conditions that do not allow for for gas turbine
engines to operate due to lack of oxygen
✔✔Thermosphere - ✔✔Highest level of the atmosphere that is the electronically
charged protection layer for earth
✔✔Machine principle - ✔✔Application of laws, principles, and theories that'll allow us to
develop machines to aid us in our daily work
✔✔Purpose of the Machine Principle - ✔✔All machines multiply force or speed and one
must be lost in order to gain the other.
✔✔Process of the Machine Principle - ✔✔1. Work is suppled to the machine (input
work)
2. Work is exerted against friction (energy is expanded)
3. Output work is done by the machine (useful work)
✔✔Effiency of a machine - ✔✔Measured by the ratio of work output divided by work
input.
✔✔Hydraulics - ✔✔Defined as the branch of science that deals with the study of liquids
in motion
✔✔Principles of Hydraulics - ✔✔1. Pascal's Law
2. Based on the idea that a confined liquid will transmit any pressure applied to it until
the pressure at any given point is equalized
✔✔Purpose of Hydraulics - ✔✔To move mechanical components accurately and safely
with ease
✔✔Components of the Hydromechanical System - ✔✔Resivoir
Filter
Pump
Pressure Relief Valve
Selector Valve
Actuating Unit
Tubing
Check Valve
✔✔Resivoir - ✔✔Contains supply of fluid used by the system
✔✔Filter - ✔✔Filters out the contamination
