Aviation Machinist's Mate (AD) Week 1 Practice Assessment

• What is defined as an element or a compound?
• Weight
• Matter
• Energy
• Force

Answer: B - Matter is defined as an element or compound.

• What is the measure of force caused by gravity on a unit or mass?
• Velocity
• Power
• Weight
• Pressure

Answer: C - Weight is the measure of force caused by gravity on a

unit or mass.

• Which type of pressure is confined and not causing motion?

• Impact pressure
• Relative pressure
• Absolute pressure
• Static pressure

Answer: D - Static pressure is in a confined space or not causing

motion.

• Which pressure is caused by motion?
• Impact pressure
• Static pressure
• Absolute pressure
• Relative pressure

Answer: A - Impact pressure is caused by motion.

• Which type of pressure is one pressure in relation to another?
• Absolute pressure
• Static pressure
• Impact pressure
• Relative pressure

Answer: D - Relative pressure is 1 pressure in relation to another.

• What is the sum of atmospheric pressure and system pressure

starting from a theoretical vacuum?

• Absolute pressure
• Impact pressure
• Static pressure
• Relative pressure

Answer: A - Absolute pressure is the sum of atmospheric pressure

and system pressure starting from a theoretical vacuum.

• Which law states that pressure applied to a confined fluid is

transmitted equally in all directions?

• Boyle's Law
• Pascal's Law
• Charles' Law
• Newton's 1st Law

Answer: B - Pascal's Law states pressure applied to an enclosed fluid

is transmitted equally in all directions.

• According to Bernoulli's principle, if a fluid's velocity increases,

what happens to its pressure?

• It decreases

• It increases
• It remains constant
• It fluctuates

Answer: A - Bernoulli's principle states that as velocity increases,

pressure decreases.

• In a convergent duct, what happens to velocity and pressure?
• Decrease velocity, increase pressure
• Increase velocity, decrease pressure
• Increase velocity, increase pressure
• Decrease velocity, decrease pressure

Answer: B - In a convergent duct, velocity increases and pressure

decreases.

• In a divergent duct, what happens to velocity and pressure?
• Increase velocity, decrease pressure
• Increase velocity, increase pressure
• Decrease velocity, increase pressure
• Decrease velocity, decrease pressure
