Why do cars not use solid fuel?
Because if they did the car would not be able to move because it is solid and 1: you could not fit it in the car hole 2: you would not get anywhere 3: we are better of using liquids like petrol and diesel
What is powder metal compaction?
Powder metal compaction is the pressing of iron and steel alloy powders into the deisred part shape through the use of mechanical or hydraulic presses. The compaction of the powder occurs within a tool set made from tool steels or carbide. The tools are fabricated to form the desired shape of the part. They are heat treated and machined or ground to very close tolerances, allowing the powder to be formed into a near net-shaped part.
The "green" part is then sintered to bond that powder particles into a solid near fully dense steel part. Once the part has been sintered, other operations, such as heat treating, machining and coating, may be performed on the part.
For a full description of the processes used in powder metal compaction see the related links below.
What process is occurring when you change a test instrument's output to agree with a known standard?
Your answer is Calibration.
What are the advantages of concurrent engineering?
Manufacturing Personnel are able to identify production capabilities and
capacities .They have thus the opportunity to inform the design group about the
suitability of certain materials on the flipsides the designer would know the
suitability of certain designs in aiding in cost reduction and quality improvement in
production/assembly process.
Early opportunities for design or procurement of critical tooling, some of which
might have long lead times.
early consideration of the Technical Feasibility of a particular design or a portion
of a design. Again this can avoid serious problems during production.
Define the efficiency of a rectifier?
The conversion efficiency n of a rectifier ckt is generally defined as
Na= dc power delivered to the load/ ac power input to the rectifier ckt. Or n = Pdc/Pac
Should solder be reheated on a circuit board?
Yes, once or twice using flux but only with prototype boards.
What project helped establish Leonardo's reputation as a creative and talented engineer?
the important painting of the Baptism of the Christ. Leonardo painted the kneeling angel and some of the background for this work.
What question have 42 as answer?
The Answer To Your Questoion Is: What Is The Answer To The Universe? It Was Asked To An ENIAC In Some Old Movie (I Forgot The Title).
In the engineering design process why would you need to repeat some steps in the process?
To have little room for errors.
How many kulli in one Larcham?
18 kulli in one larcham
1 kulli =151.25 sq.ft.
1 larcham= 2722.5 sq.ft

Is gear cycle better or normal?
gear cycles are better than normal cycles because gear cycles are comfotable for riding as compared to normal cycles
What is difference between Earned Value and VOWD?
Earned value is the physical percent complete x the approved budget. Value of work done is the percent complete x the estimate at completion. VOWD is used as an accrual mechanism which is dependent on the forecast - thus the figure will be adjusted upon receiving an invoice/actual being realised, earned value is a physical percent complete represented in terms of the budget applied universally and is absolute.
When should you act on your own initiative in engineering?
Acting on your own initiative is always a good idea as long as you are not harming a person or outcome. Try to figure out things for yourself and this will make you more successful.
What are the uses of tissue engineering?
1) To create the product to improve tissue function or heal tissue defects.
2) To replace damaged or diseased tissue.
Satellite surveying is a form of land survey that uses location information provided by the GPS satellite system to track the location of each reference point.
What is the time complexity of adding three matrices of size NXN cell-by-cell?
O(N^2)..
Explanation :
For this question its going to use 2 for loop;
so it vil be executed n^2 time,
Ex:
n=5; then that vil be executed 25 time;
So answer is O(N^2)
What are the advantages of Daniel cell?
It is free of local action, because its negative terminal, the zinc rod is amalgamated.
What metal has lowest thermal conductivity?
Mercury, apparently
Bismuth has the lowest thermal condctivity of metals that are solid at room temperature.
What do you mean by resultant current?
The sharing of current between different components in an AC circuit
What is theoretical engineering?
Speaking as a young, self taught software engineer, Googling the issue it seems that there is no straight answer yet. Lots of people shoot the idea down as it being physics but that isn't really true since:
- Physics is mostly about studying how the world works, not getting the most out of it
- Genetic engineering, highway engineering, software engineering, social engineering etc... All have little to no direct use of "pure" physics to my knowledge.
Personally I think that when theoretical engineering is defined it will have a general thinking process that goes as follows:
- We have this starting point and this desired outcome. The relationship can be explained by this piece of notation that looks like maths but isn't.
- We will need components that follow these not exactly mathematical behaviors.
- And we'll combine them as described here.
