AUMT 1416SEC4 Exam Questions Part 3 Questions with Correct Answers
Question 1:
The magneto-rheological fluid used in some shock absorbers and struts contains:
Answer:
Small, suspended metal particles.
Question 2:
The main purpose of shock absorbers and struts is to:
Answer:
Control spring action.
Question 3:
All of these statements about gas-filled shock absorbers are true EXCEPT: A hydrogen gas
charge is used in most shock absorbers and struts.
The gas charge creates a mild boost in spring rate.
The primary function of the gas charge is to minimize aeration of the hydraulic fluid.
A gas-filled shock absorber provides continuous damping action with very little wheel
movement.
Answer:
a. A hydrogen gas charge is used in most shock absorbers and struts.
Question 4:
Compared to a conventional shock absorber, a heavy-duty shock absorber has:
Answer:
A high-quality seal for longer life.
Question 5:
Electronically controlled shock absorbers and struts:
Answer:
Contain an electronically controlled actuator in the top of each strut.
, Question 6:
Adjustable struts:
Answer:
Provide softest ride with a No. 1 setting.
Question 7:
Travel-sensitive struts:
Answer:
Bypass some of the oil past the piston when compressed.
Question 8:
All of these statements about shock absorber design and operation are true EXCEPT:
The oil flow through the orifices and valves is matched to the spring's strength and deflection
rate. A typical shock absorber may have 70 percent of the total control on the extension cycle.
During jounce wheel travel the piston moves upward in the shock absorber lower tube unit. A
nitrogen gas charge in a shock absorber prevents oil foaming.
Answer:
c. During jounce wheel travel the piston moves upward in the shock absorber lower tube unit.
Question 9:
Load-leveling shock absorber systems:
Answer:
May be pressurized from an onboard air pressure tank.
Question 10:
Which of the following statements is TRUE concerning gas-filled shocks? The gas is compressed
during shock operation.
The gas is contained at the bottom end of the shock tube. The gas is not allowed to mix with
the oil.
The gas is intended to help prevent excessive shock movement.
Answer:
a. The gas is compressed during shock operation The gas to return the shock to its rest position.
compresses
expands heats
