What are the types of isolator?
there are two types mainly...
off load and on load
on load isolators are those which can break the circuit when the supply is still there.
off load breakers cannont do that. the can only operate when there is no supply.
Difference between rapture disk and psv and relife valve?
Rupture disks and pressure safety valves (psvs) are both types of relief valves. Rupture disks are thin sheets of metal that break at a designated pressure and can only be used one time. Pressure safety valves also relive at a specified pressure, but work by a spring and can relieve multiple times with little or no damage to the relief device.
Planning is looking a head and controlling is looking back?
planning may be looking ahead whilst controlling is ensuring the planning comes to a sucessful conclusion
How do you do for phase sequence protection at three phase motor operation?
motor is designed to operate in forward and reverse direction for the purpose of elevator. Phase sequence protection is not required.
What is 847 in engineering notation?
Engineers tend to use the most appropriate notation for a given situation, and in many situations, 847 will be a perfectly fine way of expressing the number 847 for an engineer.
The expected answer to this question most probably is 0.847E3 though, which indicates a base number (0.847) is to be multiplied by 10 to the power of 3 (103=1000), thus 0.845E3 = 0.847 * 103 = 847.
Engineering notation becomes more appealing with much larger numbers, or numbers much smaller than one (regardless of the number's sign). As a rule of thumb, you should consider using engineering notation for numbers that make you squint and count the zeroes. Straight-forward numbers such as 847 do not benefit from such complication. Engineers are pragmatic people.
Is it possible to flip a 747 upside down?
Yes, at least once, and was actually done on a demonstration flight of the Boeing 707. It should be possible on the 747 as well, but there might be some gravity-fed equipment you would risk damaging in the process.

Why is engineering drawing considered the graphical language of engineers?
An engineering drawing, that is, a technical drawing or set of schematics that follow international standards of commonly recognized de-facto rules can be understood without language, and with a minimum amount of words written on the drawing.
The drawing conveys a lot of information that would be error prone and ambiguous when conveyed through human language.
Why are blow out panels used in aircrafts?
A rupture disc or blow out panel is a non-reclosing pressure relief device that protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
Rupture discs are commonly used in petrochemical, aerospace, aviation, defense, medical, railroad,nuclear, chemical, pharmaceutical, food processing and oilfield applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the rupture disc will burst. Rupture discs are very often used in combination with safety relief valves, isolating the valves from the process, thereby saving on valve maintenance and creating a leak-tight pressure relief solution.

He says he comes up with it after losing to Aokiji, but he first uses it and mentions it against CP9's Blueno
How much speed of wind is required to move 1 Kg?
No simple answer - it depends on the item's surface area and its aerodynamic coefficient.
Easy move - a ten square metre sail will move a small boat in a light breeze.
Hard move, a square block of uranium on a checkerplate floor.
More info will help.
What are advantages and disadvantages of direct-view storage tube?
The contrast in a DVST monitor is not sharp
They ordinarily do not display color .
Selected part of the picture can not be erased
The erasing and redrawing process can take several seconds for complex pictures.
What is the difference between stress and strain and tension?
Stress is the tension/compression force per unit area.
Strain is the ratio of change of length to the original length, due to applied force.
Tension is the applied force which tends to elongate the body.
