When do design engineers start on the design improvement step?
Answer:
as soon as there is a design to improve
Explanation:
As a design engineer, I started on the "design improvement" step as soon as I had an initial conceptual design.
__
Then, I started that step again when my boss told me, "make it better."
_____
The more interesting question is, "when do you stop the design improvement step?" (Judging by the constant barrage of software updates, that answer is, "never.")

The minimum safe working distance from exposed electrical conductors
a. is unlimited
b is at least 2 feet
с. depends on the amount of voltage
d. only a few inches
e. depends on the type of PPE you are wearing
Answer:
The minimum distance for safety from exposed electrical conductor depends on the voltage.
Explanation:
Electric charges leak from the electric conductor when voltage across the conductor is increased.
For safety, the distance which once should maintain depends on the voltage on which the conductor is working.
For general purposes, it is assumed to be safe when one is about 2 feet distant from the conductor.
Therefore, the correct answer should be c. depends on the amount of voltage.

What is a two stroke engine and what is a four stroke engine, please keep the definitions as simple as can be and please explain the processes for each.
Make sure to also decsribe the strokes for each engine and
where it takes place in the engine.
Lastly, give some characteristics of the engines like which one gets hot faster
or which one is quieter or slower, etc.
This question is worth 65 points.
Answer:
A two-stroke engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston during only one crankshaft revolution.
A four-stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.
process for two stroke engine
This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions.In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the "power band". Compared to four-stroke engines, two-stroke engines have a greatly reduced number of moving parts.
process for four stroke engine
A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed:
Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston.
Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage.
Combustion: Also known as power or ignition. This is the start of the second revolution of the four stroke cycle. At this point the crankshaft has completed a full 360 degree revolution. While the piston is at T.D.C. (the end of the compression stroke) the compressed air-fuel mixture is ignited by a spark plug (in a gasoline engine) or by heat generated by high compression (diesel engines), forcefully returning the piston to B.D.C. This stroke produces mechanical work from the engine to turn the crankshaft.
Exhaust: Also known as outlet. During the exhaust stroke, the piston, once again, returns from B.D.C. to T.D.C. while the exhaust valve is open. This action expels the spent air-fuel mixture through the exhaust valve.
characteristics of two stroke and four stroke engines (which one gets hotter)
Since there are twice as many power strokes during the operation of a two-stroke engine as there are during the operation of a four-stroke engine, the engine tends to heat up more, and thus is likely to have a shorter life. Also, in the two-stroke engine lubricating oil must be mixed with the fuel.

What is a two stroke engine and what is a four stroke engine, please keep the definitions as simple as can be and please explain the processes for each.

Match the benefit of full synthetic oil with engine conditions: All engines exhibit wear over time.
Answer:
Inside the following section, certain advantages or perhaps the benefits of full synthetic oil are listed.
Explanation:
There seem to be a variety of possible reasons why it would be safer for synthetic oil. Even though synthetic oil becomes largely man-made, there's also a lot of fantastic monitoring over all of the chemical or oil composition. This would have additional advantages for your engine because synthetic oil could be combined with various additives to improve the performance as well as sanitation of each fuel.When exchanging information with anyone involved in the collision, you should _____.
