Aeromedical Factors With Comprehensive
Explanations and Solutions With Thorough
Explanations and Correct Responses WITH
MULTIPLE QUESTIONS AND THE CORRECT
ANSWERS
the mechanical amplification of vibration by the body occuring at specific frequencies is
called - CORRECT ANSWER- -Natural body resonance
A loss of mechanical energy in a vibrating system. causeing the vibration to slow down is
know as - CORRECT ANSWER- -Damping
When does the highest level of vibration occur during flight - CORRECT ANSWER- -Hover to
flight and flight to hover
What are the short-term effects of vibration on the body - CORRECT ANSWER- -Fatigue,
respiratory effects, circulatory effects, motion sickness, disorientation, and pain
How does vibration cause fatigue? - CORRECT ANSWER- -Vibration causes the muscle to
contract (exercise)
For example, vibration placed on both calves of a standing subject resulted in the subject
experiencing the sensation of leaning forward (constant exercise)
The result of vibrating frequencies in the diaphragm will cause - CORRECT ANSWER- -
Respiratory effects
,The result of these "artificial respiration" could lead to hyperventilation if the diaphragm is
vibrated at 4-8 hertz
What are the long-term effects of vibration on the body - CORRECT ANSWER- -Raynaud's
disease, Backache/back pain, and kidney/lung damage
TRUE OR FALSE:
Backache/back pain in aircrew member may result at an earlier age than normal -
CORRECT ANSWER- -TRUE!
Backache/back pain in aircrew member may result at an earlier age than normal. The
lumbar spineis subjected to higher pressures during aircraft operation because the weight
of the torso on that part of the spine while sitting.
what is Raynaud's Disease? - CORRECT ANSWER- -Raynaud's Disease (White finger)
occurs to the hands after prolonged exposure to vibration from power tools, jackhammers,
or other such equipment that vibrates at high frequencies. Trauma occurs in the arterioles
and nerve endings in the extremities and limits the blood flow to that portion of the
extremity
Identify the effects of vibration on vision during flight - CORRECT ANSWER- -Vision could be
affected due to vibration in the aircraft; visual instruments may be difficult to read. Helmet
mount or night vision devices may vibrate at 4-12 Hz
At what level is speech distorted from the affects of vibration - CORRECT ANSWER- -
Speech can be distorted during oscillations of 4-12 Hz. Above 12 Hz, speech becomes
increasingly difficult to interpret
__________ is the mechanical radiant energy that is transmitted by __________ pressure
waves. - CORRECT ANSWER- -Sound, longitudinal
, Newton's First Law - CORRECT ANSWER- -(Law of Inertia) an object in motion tends to stay
in motion & an object at rest tends to stay at rest unless acted upon by an outside force.
Newton's Second Law - CORRECT ANSWER- -Force = Mass x Acceleration
Newton's Third Law - CORRECT ANSWER- -For every action there is an equal and opposite
reaction
what is 1G (Gravity) - CORRECT ANSWER- -32.2 Ft/sec2
What is Inertia - CORRECT ANSWER- -the resistance to a change in the state of rest or
motion
Acceleration - CORRECT ANSWER- -The (increased) rate of change of velocity with respect
to time. Acceleration of gravity continues until terminal velocity is reached.
Deceleration - CORRECT ANSWER- -A reduction in the velocity of a moving body with
respect to time (negative acceleration)
What is the Tri-axial Reference System - CORRECT ANSWER- -Identifies the direction in
which the body receives accelerative forces. (X,Y, & Z axes)
X-axis - CORRECT ANSWER- -the axis through the chest to back
Y-axis - CORRECT ANSWER- -the axis across the shoulders
Z-axis - CORRECT ANSWER- -the long axis along the spine from head to foot
