Answer / kumar

as per formulae,

stress(newton/sq.m) = load/unit area

Answer / hari prasad

Stress is the internal resistance, or counterfource, of a
material to the distorting effects of an
external force or load. These counterforces tend to return
the atoms to their normal positions.
The total resistance developed is equal to the external
load. This resistance is known as stress.

Answer / ram krishan singh

the resistance offered by the body per unit area aginst
failure is knon as stress

Answer / kalesh

Whenever an external force is acting on a body, an internal
resistance is setup in that body. This internal resisitance
offered by the body per unit area is called stess.

Stress = load/unit area.

The unit is N/mm2 (S.I.Unit)

Types : 1.Tensile stess
2.Compressive stress
3.Shear stress
4.Bending stress

Answer / karthick

stress is the internal force devloped inside a body due to
the application of external force

Answer / vikas

the load applied per unit area on a body is "stress".

stress(newton/sq.m) = load/unit area

Answer / m. sohail iqbal

When an external force acts upon a body, an internal
resistance is setup in that body. This internal resistance
offered by the body per unit area is called stress.

Stress = load/unit area.

The unit is N/mm2 (S.I.Unit)

Types : 1.Tensile stress
2.Compressive stress
3.Shear stress
4.Bending stress

Answer / shailesh telang

it is internal resisting force per unit area of body

types of stainless steel.why does this called stainless.what is passivation related to SS? What is sensitisation in stainless? Examples of diffrent type of steel e.g. austenatic,martensite,ferritic etc. 304,303,316. How to get rid of carbide formation in SS and stablization in SS.(347 etc.)Different type of heat treatments. Iron carbon diagram. Nelson chart with respect to corosion. Diffrent type of corosion and causes. Carbon equvalent number. Welding related questions.(requirement of post and pre heating in welding). welding of SS. If you have pre experience in maintenance then Material and welding related questions will be there. Then various types equipment in plant (a) static (b) rotatic in pumps and compressor,turbines funda of balance drum and balance disc, balancing line. Impulse wheel, wheel chamber pressure and its effect on turbone health if this increases. Thermal expansion of turbines and with respect to how foundation bolting are designed. Fixing of lower casing before dismantling. Most important shaft alignment and balancing of rotating equipment,classification of static and rotatic equpment used in process plants. Materials for diffrent services as refinery plants fertilizer plants, cement plants, sulphur plants, crude oil with higher sulphur services, then third important thing is codes, standards and recommended practices of diffrent organisation like ASTM,ASME,API,TEMA,BIS,IS,ISO,NPFA,OISD etc. diffrent type of work permit systems fire and safety point of view.
