Mechanical Engineering

I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.

In an application of pressure reduction, the warm up valve (bypass valve) is used to warm the steam line, within recommended time frames, before the control valve is placed into operation.

A steam control valve should not be used for warm up of a steam distribution line.

There are no operational scramjets in existence as yet. Scramjet engines have been tested but the problems associated with producing an operational scramjet have proven to be beyond technological capabilities to date. See the Wikipedia link below for additional information.

i think it is better for everyone it is nt only suitable for girls it sis also suitable for boys but but both of character have to be work hard in this field bcoz as i knw ma father is laso a senior engg in mechanical firstly he passed out his 12 th frm cbse board the he had done his b.a after that iti in tool and die making today he is earning lot of amt.in pune guys if u want to do the mechanical engg then just focus on that and after that if u want to earn the the huge amount the just go to pune because in delhi here is nt good job for mechanical engg just go to pune see a large no automobile companies are overthere TATA,Mercedes, ets a large no of automobiles companies overthere there lot of girls doing work as senior mechanical engg guys if u want to do then just focus on that field.

The packing is located under the handle there is either a stuffing box or a nut over the valve stem

Resistance against separation of the atoms of each show.

CFM is a way of saying ft3/min, or cubi feet per minute. It is a measure of the volume of air a fan can move in a minute. Generally speaking, the higher the CFM, the more powerful a fan it is. Or, if you happen to be in the aircraft industry, CFM refers to the company CFM International, a 50-50 joint venture between General Electric of the United States and Snecma in France.

A rectifier is an arrangement of diodes (devices that only allow current to flow in one direction), half-wave or full-wave, that converts AC to pulsated DC. A capacitor (condenser) is used to smooth out the pulsated DC for a more true DC supply.

A transformer is usually comprised of two coils of wire around an iron core that changes the ratio of input voltage/current to output voltage/current. It does this by induction (a magnetic field crossing through a coil of wire producing electricity). The Primary coil (the input) usually is a bit thicker and has less windings than the Secondary coil (the output).

Isometric view is a two dimensional representation of a three dimensional object or space. It is often used in technical drawings, such as architectural, engineering and patent drawings. It is similar to perspective view, yet isometric drawings do not converge at a vanishing point. Since perspective is an optical illusion that skews the lines and dimensions of an object, it cannot be used to convey technical data (i.e., the exact size and measurements of an object, surface or space). In isometric drawings, however, the lines remain parallel and proportionate to one another. It conveys an illusion of three dimensional space without modifying the dimensions and scale of an object. Therefore, it can be used as a scaled technical drawing.

Visually, an isometric view consists of two elevations (A and B) that are adjoined at one side (the y axis) and a plan view (C) that is joined at the top or bottom of elevations A and B. All vertical lines are drawn at an angle that is perpendicular to an imaginary horizon line (the x axis). All horizontal lines, however, are rotated along the y axis at a constant angle (usually 30 or 45 degrees). If the horizontal lines in elevation A are rotated to 30 degrees (taken from the x axis), then the inner angle will be 60 degrees (taken from the y axis). On the opposite side of the y axis, elevation B is mirrored at the same angle (30 degree outer and 60 degree inner). The sum of the inner angles (60 + 60) then forms the angle of the adjoining plan C (120 degrees). For a 45 degree isometric, the inner angles of elevations A and B are each 45 degrees and the adjoining angle of plan C is 90 degrees.

There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test.

On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.

Boron (B), Silicon (Si) and Arsenic (As) are all metalliods.

1) Check that your work area is clear or clean up before you start.

2) Clear away waste materials safely.

3) Check for contamination on bench tops.

4) Check for slip/ trip hazards.

5) Checking that tools are safe to use before returning them to the storage area or report defects for the technician to repair.

6) Return safety equipment to the correct storage area.

Probably somebody threw a vine over a stick...

a gate valve is a positive shut off valve for liquids and gases and should only be used in the fully open or closed positions, different temperatures and pressures must be considered to insure the correct type of valve to install. a sluice valve is a non-positive shut off valve used for heavier materials such as stone,grain,sand,etc.

The answer can be split into a few different sections as you can take each part of the bearing and describe how each component is made. First let's take the balls of a ball bearing as these are quite an essential part! First of all a piece of thick wire is fed into a machine, the wire is cut down by chopping off pieces from both sides until it is quite small.

Deep groove ball bearings are used in a particularly wide variety of applications. Consequently, they are available in many executions and sizes.

What is the formula of calculating tower crane load chart.

-------------------------------------------------------------------------------

All cranes should have a load chart/ information plate mounted near the operator's position, or in the operator's cab. Also, an operator's manual should be located close at hand as well, often on the back or under the operator's seat.

It's whatever the designers make them. It means that for an elevator for instance that the cables can take a much higher load than the elevator is rated for before the cables will snap. If the cables can take double the rated load then the elevator is said to have a safety factor of two.

26 inch......means 650 mm

rub the bearing gently with a rag soaked in olive oil

Structure that contains the cockpit for the pilot.

Structure that allows aircaft to carry cargo, passengers, and equipment.
