Honing is a sort of hole finishing operation performed after drilling. The honing tool is a multipoint cutting tool. There will thin projections parallel to the length of tool extending from one cross section to other. When the tool is inserted into the hole, a loading is given on the cross section of the tool which extends a spring attached to the projections pushing the "abrasive cutting edge" out side and then it is rotated so as to give finishing. This method is generally use in the cylinder of IC engines..

Rough sketch:-

Dotted arrows show the 2 peripheries of the cutting tool and "equal to sign" shows edges of abrasives. The pushing of spring radially connected to the centre pushes the cutting edge of abrasives out which enables finishing operation

You may not realize it, but the products of chemistry play a big role in our daily lives. Chemists and materials scientists create the building blocks for medicines like Prozac or products such as plastic bags. Even the chocolate, marshmallow, and banana flavors of the processed food you eat were created in a lab by food chemists.

Chemists and materials scientists working in applied research come up with new products for industrial, commercial, and medical use.

Consumer circuit is a circuit that fixed between distribution line and consumer load control and protection unit is attached in order to prevent overload, leakage and short circuit.

yield is the breaking point and tensile strength is what it is rated at per square inch

This enormous electrical discharge is caused by an imbalance between positive and negative charges. During a storm, colliding particles of rain, ice, or snow increase this imbalance and often negatively charge the lower reaches of storm clouds. Objects on the ground, like steeples, trees, and the Earth itself, become positively charged-creating an imbalance that nature seeks to remedy by passing current between the two charges.

gland condenser is a type of condenser in which steam which is coming from d turbine is used for the heating of demineralised water and then this water is sent to the boiler so boiling of hot water consumes less coal and thus we get benifit of it

Sealing steam is as the name says - it provides a seal for turbines that exhaust into a vaccum condenser, hence creating a better vaccum, and preventing non condensables from entering the system sealing is of two type say positive sealing and negative sealing used for perffect sealing positive used in hp side and negative in lp side.

If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).

Time = Distance / Speed "/" means divide Calculate the average speed then put it into the equation. For example: Time (hours) = 42 miles / 86 miles per hour Time = 0.49 hours Time = 29.4 minutes (60x0.49)

Indolene is a form of gasoline used in testing because it is standardized and has no additives.

Indolene gasoline is used for the US Federal Test Procedure (FTP) to certify vehicles for emissions rather than commercial gasoline. Indolene fuel used in certification typically has a sulfur content below 50 parts per million (ppm). On the other hand, commercial gasoline sulfur content ranges between 30 and 1000 ppm throughout the US with an average of about 300+/-50 ppm.

Indolene gasoline results in reproducible tailpipe emissions from a test vehicle. Commercial gasoline results in a wide range of emissions. The emissions differences are attributable largely to the disparity in gasoline sulfur content.

Often interchangable in functions. Scientists are generally those who specialise in a particular disipline, often at the analythical or resarch stages of a project. The original engineering qualifications were issued to marine steam-engine operators as there were too many ships being lost due to boiler explosions. Professional bodies set standards for entry, academic bodies set standards of engineering qualification levels - Certificate, Diploma, Degree etc

The famous Big Allis ( an Allis-Chalmers generator made originally in l959) and possibly still in use though re-armatured a number of times, was rated-after preliminary tests at the Argonne National Labs-they intended to use it for atojm-smashing , not regular power generation, at get this, l5 BEV. BEV? Billion Electron Volts, don"t spend it all in one place, it was claimed the exciters or starting motors alone drew l5 MEV (Million electron-volts) Popular Mechanics sang the praises of this famous generator that could (Jack the energies up to l5 BEV!) There you have it. There are probably higher powered units for purely experimental work bit iI"ll stand by Big Allis.

Carbon is primary hardening element in steel. Hardness and tensile strength increases as carbon content increases upto 0.85%. Ductility and weldability decreases as carbon content increases.

If the solution of carbon and liquid iron is solidified slowly the carbon tends to separate out in the form of graphite flakes (Grey cast iron). It is easily machinable. If the same iron is cast and colled quickly, it is hard and has a higher tensile strength, is difficult to machine (white cast iron).

An example of an "interference fit" is when you have a pin that needs to go into a slightly smaller hole. The difference may be only 2/1000 inch (machinists measure parts in thousandths of an inch). In this case, the pin won't just slide into the hole, but needs to be forced, usually with a devise called a "press." . The usual purpose of an interference fit is to join two mating parts together in a way that they won't come apart without having to use other, more normal, fastening methods. For an elementary example of an interference fit and purpose, if you drive a nail half-way into a wall so you can hang something onto the part of the nail that sticks out of the wall, there is an "interference fit" between the nail and the new hole in the wall that the nail made.
