ASTB Mechanical Exam Questions and
Answers 100% Pass
Venturi Effect - ✔✔Reduction in fluid pressure that results when a fluid flows through
a constricted pipe (narrows)
Bernoulli's Principle - ✔✔As the speed of a moving fluid increases, pressure within the
fluid decreases
Total Pressure Formula - ✔✔Total Pressure = Dynamic Pressure + Static Pressure
Boyle's Law - ✔✔If a gas remains at constant temperature, the volume is inversely
proportional to the pressure
What to the Pressure when a gas is compressed to half its original volume? -
✔✔Pressure will double
Dynamic Pressure - ✔✔The pressure on a body from a fluid when the fluid is moving
(kinetic)
Static Pressure - ✔✔The pressure on a body from a fluid when the fluid is at rest
(potential)

,Voltage Defined - ✔✔Electrical measurement of force
Current Defined - ✔✔Rate of an electrical current between circuits
Voltage Formula - ✔✔Voltage = Current x Resistance V = I x R
Balloon - ✔✔Air pressure inside is greater than atmospheric pressure outside
How are Density and Pressure related? - ✔✔Pressure is directly proportional to density;
if one rises, so does the other
Density Formula - ✔✔P = M/V
Particle Collisions Available Energy - ✔✔The available energy is the energy used to
produce new matter from the kinetic energy of colliding particles
Particle Collisions Momentum - ✔✔Due to conservation of momentum, system of two
particles with net momentum may not convert all their kinetic energy into mass,
resulting in an available energy that is always less than or equal to the kinetic energy of
colliding particles
Isothermal Energy - ✔✔Remains constant
Heat Transfer with conductivity - ✔✔Hot things expand and cold things compress
(water is exception)

, Pendulum - would a wrecking ball take longer to swing at a higher or lower length -
✔✔A lower length - the longer the rope the longer the swing
Pendulum - when does a pendulum have the most kinetic energy? - ✔✔At the bottom
of the swing
Pendulum - when does a pendulum have the most potential energy? - ✔✔At the highest
position of the swing
Mass is determined by - ✔✔Mass = Weight x Gravity
Gravity on Earth - ✔✔9.81 or use 10
Newton's Law of Gravity - ✔✔Every particle attracts every other particle
Potential Energy formula - ✔✔PE = mass x acceleration of gravity x distance (height) PE
= mgy
Kinetic Energy Formula - ✔✔KE = (1/2) x mass x velocity ^squared KE = (1/2) x m x
v^2
Potential Energy Defined - ✔✔Energy stored in an object
Kinetic Energy Defined - ✔✔Energy in Motion
Work Defined - ✔✔Work is the energy required to move or change an object
Work Formula in terms of Energy - ✔✔Work = Force x Distance
