Questions with Answers
The boiling point of a given liquid varies - -directly with pressure
- Which of the following is NOT considered a method of heat transfer? - -
Diffusion
- An engine that weighs 350 pounds is removed from an aircraft by means of
a mobile hoist. The engine is raised 3 feet above its attachment mount, and
the entire assembly is then moved forward 12 feet. A constant force of 70
pounds is required to move the loaded hoist. What is the total work input
required to move the hoist? - -840 Foot pounds
- Which condition is the actual amount of water vapor in a mixture of air and
water? - -Absolute Humidty
- Which will weigh the least? - -35 parts of dry air and 65 parts of water
vapor
- Which is the ratio of the water vapor actually present in the atmosphere to
the amount that would be present if the air were saturated at the prevailing
temperature and pressure? - -Relative humidity
- The speed of sound in the atmospher - -varies according to the frequency
of the sound
- If the volume of a confined gas is doubled, the pressure will? - -be reduced
to one-half its original value
- If the temperature of a confined liquid is held constant and its pressure is
tripled, the volume will - -remain the same
- How much work input is required to lower a 120-pound weight from the top
of a 3-foot table to the floor? - -360 foot-pounds
- What atmospheric conditions will cause the true landing speed of an
aircraft to be the greatest? - -High temperature with high humidity
- If the fluid pressure is 800 PSI in a 1/2-inch line supplying an actuating
cylinder with a piston area of 10 square inches, the force exerted on the
piston will be? - -8,000 pounds
, - What force must be applied to roll a 120-pound barrel up an inclined plane
9 feet long to a height of 3 feet? - -40 pounds
- Which statement concerning heat and/or temperature is true? - -
Temperature is a measure of the kinetic energy of the molecules of any
substance
- What is absolute humidity? - -The actual amount of the water vapor in a
mixture of air and water.
- The temperature of which humid air must be cooled at constant pressure
to become saturated is called - -dewpoint
- If both volume and the absolute temperature of a confined gas are
doubled, the pressure will - -not change
- If all, or a significant part of a stall strip is missing on an airplane wing, a
likely result will be - -decreased lift in area of installation at high angles of
attack
- The purpose of stall strips on airplane wings is to - -ensure that the wing
root areas stall first
- An airplane is designed to produce life resulting from - -negative air
pressure blow the wing's surface and positive air pressure above the wing's
surface along with the downward deflection of air
- The purpose of aircraft wing dihedral is to - -increase lateral stability
- Aspect ratio of a wing is defined as the ratio of the - -wingspan to the
mean chord
- A wing with a very high aspect ratio will have - -a low stall speed
- The desired affect of using winglets on an aircraft's wingtips is to - -
increase lift to drag ratio
- Which of the following is newton's first law of motion, generally termed the
law of inertia? - -Every body persists in it's state of rest, or of motion in a
straight line, unless acted upon by some outside force
- When computing weight and balance, an airplane is considered to be in
balance when - -the average moment arms of the plane fall within CG range
