Answer / jeevan dhole

torque is a resistive force producing by rod material about
its own axis when external twisting coupled force is applied
on it.............

moment is the rotational displacement produced by the rod
member about any point on member when external point load or
couple is applied on it..............

Answer / pradeep berry

Pressure is in balloons, pressure is in cylinders, pressure
is active when enclosed,
while Force is push, pull, moving a thing etc.
this is what is naturally happening and will indicate the
difference.

Answer / nayyer

Stress is basically restoring force per unit area.The restoring force is produced on the application of external force, while as pressure is simply force acting per unir area on a surface.

Answer / viplava

stress is internal resistance due to applied load, where as pressure is external force applied upon the surface.
stress may be in tension or compression or shear, pressure is only only compression.

Answer / vivekdoke

pressure and stress both are same
but Pressure is sclar quantity and stress is scalar
quantity e.g Normal stress shear stress

Answer / rajeev mehta

stress always act on solids and pressure always act on liquid

Answer / ravi kumar singh

STRESS is defiend as the ressistance force applied against deformation is known as stress.

but pressure =acting force/unit area

Answer / praveen

Stress deals with the application of load while pressure
deals with the external disturbances or the load.

stress can be stated as:
stress=load applied/Area of cross section

while pressure can be stated as:
pressure=force or external disturbance/Area of cross section

Answer / mj

Stress is tensor whereas pressure is scalar

Answer / engr. safeer khan

stress and pressure are same thing but stress is internal
resistance of solids against applied force
while
pressue is used for liquid and gases which is also an
internal resistance against applied force

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.
