How is metric thread pitch measured?
Metric thread pitch is measured directly from crest to crest of the thread form.
For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM.
Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.
What size of generator to run 5.5kw 400v 50Hz motor?
You need a 5.5kw generator to run a 5.5kw motor.
How is wool comparatively stronger than steel?
wool has many crimps so it can carry steel and it is elastic
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load.
The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage.
The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.
How a Cathode Ray Oscilloscope is used to measure Alternating current?
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.

What is range in cooling tower?
Range is the difference of cooling water inlet and cooling water outlet temp
Why dams must be constructed so that they are much thicker at the bottom than the top?
Because the water pressure at the bottom of the dam is much more than the top.
What is a redundant constraint?
A constraint which is not required or is extra, presence or absence of such a constraint does not effect the solution of problem
What is fracture toughness of ceramics?
It depends on the ceramic. Most ceramics have fracture toughness between 0.7 AND 1 MPa - m^1/2. Some are lower, and some higher, up to 5 MPa-m^1/2
Why need to study industrial engineering?
Industrial Engineering is a extended branch of Mechanical engineering but now stands a separate entity. It involves work study, method study, time study, optimization techniques, value engineering. It focuses on improving the way a work or job is done. If one wants to improve an activity, optimize an activity either by man or machine, Industrial Engineering tools offer solution.
What are the four essential functions of an automatic process control system?
1. to protect the plant
2. to support the plant
3. To respons to changes in the plant
4. to monitor process parameters
How much clearance is need around 18000 volts to keep it from jumping to ground?
18000 volts clearance
If oil is replaced by air in a hydraulic system would the hoist still operate?
Practically it won't, be the air will get compressed, and then the hoist will not work. Read Pascal's principle to check if my answer if correct.
How was the Bible influential in precipitating the age of industry?
While the Bible states that a worker is due his wages, there isn't a mention of railroads or infrastructure that precipitated the Industrial Revolution.
Where do you use reciprocating pumps in daily life or in industrial applications?
Daily life you use reciprocating pumps buy using your water faucet, pumping gas or simply using a suringe for medicine.
Is titanium stronger than platinum?
Yes.
In fact, titanium was the strongest material on earth until just recently.
What is an h stamp on a boiler?
American society of mechanical engineers has a classification of pressure vessels. Certain type of the boilers have H stamp according their classification, and this stamp is required by local authorities in order to get boiler approved for installation.
What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection.
Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
What is the importance of string diagram in industrial engineering?
it is useful for analysing the movements in short cycle repetitive jobs.
