Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

The answer is not formulatic. There will be a parabolic shape from the dead load and a discontinuity at the point load.
Shock load is a machining term. Shock load is when a sudden intense force is placed on the parts of a machine. The machine often cannot handle the pressure.
A Catchpot (GB Pat No 2302394) was invented by UK inventor Dennis Henson. A Catchpot is a container device used to catch some of the water flowing from float operated water valves. The Catchpot has bleed holes and internal siphon's and is usually attached to the lever arm of the valve. The Catchot's purpose is to create a delay in the opening and closing of the valve and improve the valves flow performance.
The word Catchpot is a registered trademark of Henson Delayed Valves Ltd.
TRIP steel is Transformation Induced Plasticity steel. It is a composite steel that consists of ferrite, bainite, martensite precipitants and restrained austenite. The austenite will transform into martensite when strained, thus increasing the strength of the steel. To stabilize the austenite you need to introduce alloy elements, usually Manganese.
1 Describe with the aid of sketches the behavior of beams and columns under load?
the beam will sag downwads
SA36 would have more traceability and QA requirements, and as a result can be used safely at slightly higher stress levels. But physically, they are the same.
What is the advantage of a posidrive screw over a slot headed screw?
A posidrive screw stays centered over the driving tool. On Slotted head screws, the screwdriver can slip easily out of the groove. A very nice kind of screw is the "TORX" head screw. With the proper torx bit, they cannot slip or strip easily while screwing them into wood or metal.
A detailed listing of the rules and principles that apply to specific welded products is called?
A weld procedure.
Why I-section beam is preferred for heavy loading?
Cross sectional shape I, giving many benefits. It is very good for giving stiffness(less deformation on loading) and to withstand higher bending moments(as a result of heavy loading) on comparison with other cross-sectional shapes of same area. Also, it is very easy to manufacture.
It will have more moment of inertia due to the distance of the flange from the centroidal axis and it have zeron eccentricity about one axis and the centrer of gravity lies inside the web.
Steel wire is commonly known as wire rope. Several layers of metal wire are twisted to form a rope. Steel is the main material used in wire rope today. The product was developed in the 1830's and was primarily used in mining when applications that could lift and hoist weights in elevators were essential.
D2 steel is a steel that is vacuum heat treated i.e raised to a high temp and rapidly cooled by a vacuum process it is an ideal steel to use for punch and dies or injection mould tools. It is a difficult material to machine and requires a special wheel for surface grinding after heat treatment. It also hardly moves during the treatment process so you can manufacture parts as thin as 2mm and leave only 0.004 for finish grinding.
D-2 is a high-carbon high-chromium tool steel manufactured for high abrasive wear applications. D-2 can be heat treated to RC 64. This grade as a low tempering temperature. Many of the common coatings can not be applied because the process temperature used to apply the coating is higher than the tempering temperature of the D-2 tool steel.
For this material, D2 tool steel, you can find detailed data check list at www dot astmsteel dot com/product/d2-tool-steel-1-2379-x153crmo12-skd11/.
The high chromium content gives this grade some stainless properties, although, it is not classified as a stainless steel.
D-2 is used for barrel liners in the plastic molding industry, die components in the metal stamping industry, and many other applications requiring high wear resistance in many other industries.

Why is it important to use a fixed common reference point for dimensioning of drawings and sketches?
It is important to use a fixed common reference point on your work peace or drawing to avoid cumulative error, i.e. if a hole is drilled using an incorrect measurement initially, then continuation to measure from the error instead of using a common reference point could result in a whole piece of work being scrapped. Also if somebody has to take over the work, they would need to understand were the dimensions were taken from to enable them to carry on with the work.
The ability of the metal to resist corrosion in atmosphere with moist.corrosion ocuurs in ferrous materials in which ferrous chemically react with oxygen forming rust or corrosion.
Corrosion can be avoided by Heat treatment and surface coating .
Thermosetting plastics (thermosets) are polymer materials that irreversibly cure, to a stronger form. The cure may be done through heat (generally above 200 degrees Celsius), through a chemical reaction (two-part epoxy, for example), or irradiation such as electron beam processing.
Thermoset materials are usually liquid or malleable prior to curing and designed to be molded into their final form, or used as adhesives.
The curing process transforms the resin into a plastic or rubber by a cross-linking process. Energy and/or catalysts are added that cause the molecular chains to react at chemically active sites (unsaturated or epoxy sites, for example), linking into a rigid, 3-D structure. The cross-linkingprocess forms a molecule with a larger molecular weight, resulting in a material with a highermelting point. During the reaction, when the molecular weight has increased to a point so that the melting point is higher than the surrounding ambient temperature, the material forms into a solid material.
Uncontrolled reheating of the material results in reaching the decomposition temperature before the melting point is obtained. Therefore, a thermoset material cannot be melted and re-shaped after it is cured. This implies that thermosets cannot be recycled, except as filler material.[1]
Thermoset materials are generally stronger than thermoplastic materials due to this 3-D network of bonds, and are also better suited to high-temperature applications up to the decomposition temperature of the material.
How much pressure in a 100 mm diameter vertical pipe with 40 meters height?
It depends on whether the pipe is open or closed and what it contains. If the pipe is full of water to a height of 40 m and open at the top, the pressure at the bottom is about 57 psig. The diameter doesn't matter.
What can Bevel gears be used in?
Bevel gears can be used to change the direction of drive in a gear system by 90 degrees
How does nitrogen help the plant?
Nitrogen is one of the most important elements in organic compounds along with Carbon, Hydrogen and Oxygen. Soil in most areas are rich in Oxygen, Carbon, and Hydrogen, but the Nitrogen composition is usually close to the bare minimum for a plant's existence. In order for a plant to truly thrive, Nitrogen enriched fertilizers are necessary.
