  1. An engineer can be an entrepreneur with highly motivated and innovative idea, also need hard working
  2. I don't think that U can fix the system. bcuz its always interact with surrounding unless u find complete insulated boundary for the system.
  3. I'm not sure but it should be very well mixed when the length is more than its diameter and turbulence flow is available.
  4. try to design of engine or gear box or heat exchanger or study about bearings
  5. What you want to present .?? modification or same design ??
  6. Wish U all Engineers.. a very happy new year...
  7. The hoop stress and longitudinal stresses are usually much larger for for thin walled cylinder that is the reason why radial stress is usually neglected.
  8. wheres ur question ..?
  9. Have you tried.. these websites.... http://jobs.freshersworld.com/category/Core-Technical http://yuwam.in/ if u didn't try these websites.. try these websites...
  10. Just see below site...... http://www.technologystudent.com/cams/crank2.htm
  11. plese check here

  12. Centrifugal casting is a casting process by which axi-symmetrical parts are made. Examples of such parts are pipes, pressure vessels, cylinder liners etc. Centrifugal Casting: In centrifugal casting, a permanent mold is rotated about its axis at high speeds (300 to 3000 rpm) as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies after cooling. The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes. The inside diameter has more impurities and inclusions, which can be machined away. Only cylindrical shapes can be produced with this process. Size limits are upto 3 m (10 feet) diameter and 15 m (50 feet) length. Wall thickness can be 2.5 mm to 125 mm (0.1 - 5.0 in). The tolerances that can be held on the OD can be as good as 2.5 mm (0.1 in) and on the ID can be 3.8 mm (0.15 in). The surface finish ranges from 2.5 mm to 12.5 mm (0.1 - 0.5 in) rms. Typical materials that can be cast with this process are iron, steel, stainless steels, and alloys of aluminum, copper and nickel. Two materials can be cast by introducing a second material during the process. Typical parts made by this process are pipes, boilers, pressure vessels, flywheels, cylinder liners and other parts that are axi-symmetric
