Question 6

FMS stands for flexible material system and is often made up of FMCs that are linked together.

Accepted Answer

FMS stands for Flexible Manufacturing System, and it is a method used to produce goods that is designed to easily adapt to changes in the product being manufactured. FMCs refer to Flexible Manufacturing Cells, which can be components of an FMS, but FMS does not stand for "flexible material system."

Question 7

Fixed automation machines are designed for a small number of products and FMCs are designed to be flexible and produce a variety of products.

Accepted Answer

Fixed automation machines are specialized for high-volume production of a limited assortment of products, whereas Flexible Manufacturing Systems (FMS) are designed to easily adapt to changes in the product type and mix, allowing for the production of a variety of products.

Question 8

Software that has been thoroughly tested and used for some period of time is usually not the cause of system problems.

Accepted Answer

Software that has been thoroughly tested and used for some period of time is generally considered stable and less likely to cause system problems compared to newly released or untested software.

Question 9

There are two conditions when software is the source of a system problem. One of the condition is when an operator enters incorrect set points or parameters into the program.

Accepted Answer

An operator entering incorrect set points or parameters into the program is a software-related system problem.

Question 10

The difference between power and signal flow on a system block diagram is that signal flows from left to right and power flows from right to left.

Accepted Answer

In a system block diagram, the convention for signal flow is typically from left to right, but there is no strict rule that power flows from right to left. Power flow is not universally defined by its direction on such diagrams and can vary depending on the specific system design and the conventions used by the diagram's creator.

Question 11

Flow of signal from a block on the left to a block on the right through four other blocks is what type of signal flow?
A) Switched path
B) Divergent
C) Linear
D) Convergent
E) Feedback

Accepted Answer

Linear signal flow describes a sequence where the signal moves directly from one block to the next in a straight line, without branching off or looping back.

Question 12

Flow of signal from one block to two or more other blocks is what type of signal flow?
A) Linear
B) Divergent
C) Convergent
D) Switched path
E) Feedback

Accepted Answer

Divergent signal flow refers to the situation where a signal from one block is split and sent to two or more other blocks, indicating a branching out or divergence in the path of the signal.

Question 13

Flow of signal from two or more blocks into a single block is what type of signal flow?
A) Convergent
B) Switched path
C) Linear
D) Feedback
E) Divergent

Accepted Answer

Convergent signal flow refers to the scenario where signals from two or more blocks or sources are combined or merge into a single block, indicating a convergence of paths.

Question 14

Flow of signal from the output back to the input is what type of signal flow?
A) Convergent
B) Linear
C) Switched path
D) Divergent
E) Feedback

Accepted Answer

Feedback is the correct term for the flow of signal from the output back to the input in a system. This process is used to control the behavior of the system by adjusting its operation based on the output.

Question 15

The term "divide and conquer" means
A) Divide the troubleshooting tasks equally between troubleshooters.
B) Make the first measurement at the first point where a signal divides.
C) Make the first troubleshooting measurement halfway between the input and output on the signal flow path.
D) All of the above

Accepted Answer

The term "divide and conquer" in the context of troubleshooting or problem-solving typically refers to breaking down a problem into smaller, more manageable parts. Making the first troubleshooting measurement halfway between the input and output on the signal flow path is a practical application of this strategy, as it helps to quickly isolate the section of the system where the problem may be occurring.

Question 16

In a divergent circuit the signal at the output of one of the divergent circuit is correct. What can you conclude?
A) The problem is between the divergent input and the input of the system.
B) All divergent outputs are correct.
C) The problem is in the divergent circuit.
D) All other divergent paths must be measured before a decision.
E) No conclusions without more data

Accepted Answer

If the signal at the output of one of the divergent paths is correct, it implies that the divergent circuit itself is functioning correctly, hence all divergent outputs should be correct.

Question 17

In a linear circuit the signal at the output is bad. The testing approach that would reduce the number of measurements is to
A) Measure the input and then check the output of each block starting from the input.
B) Make the first measurement at the output of the block half way between the input and output.
C) Measure the signal at each block output starting at the output.
D) None of the above.

Accepted Answer

The approach of making the first measurement at the output of the block halfway between the input and output is a form of binary search. It quickly isolates the half of the circuit where the problem exists, reducing the number of measurements needed to find the faulty block.

Question 18

In a convergent circuit with three switched inputs, the signal at the output is bad when the switch is on the first convergent input. When the switch is changed to second of the convergent inputs the output is correct. What can you conclude?
A) The switch could be bad.
B) There is a problem between the first convergent input and input to the system.
C) There is a problem between the convergent switch and the output of the system.
D) Both A and C.
E) Both A and B

Accepted Answer

The issue being isolated to when the switch is on the first convergent input suggests a problem specific to that path, which could mean either the switch itself is faulty (A) or there's an issue in the connection between the first input and the rest of the system (B). There's no indication of a problem between the convergent switch and the system output since the output is correct when the switch is on the second input, ruling out (C).

Question 19

If two symptom are present that are unrelated that means that
A) A single component may have failed in two different circuits or modules.
B) Two component may have failed in the same circuit or module.
C) The problem is in a convergent circuit.
D) The problem is in a divergent circuit.
E) None of the above

Accepted Answer

A single component may have failed in two different circuits or modules.

Question 20

When using funneling as a part of the troubleshooting process you would
A) start with bracket narrow and move them to a wider separation.
B) start with tests that focus on replacing sub -system components and modules
C) start with tests that focus on front panel control settings.
D) start with tests that focus on measuring signals to verify the symtoms.
E) None of the above.

Accepted Answer

The answer of When using funneling as a part of...
