Mechanical Engineering
Forum is an online discussion forum where youth or even the experienced professionals discuss their queries related to and get answers for their questions from other talented individuals. An online discussion can be started by asking questions, helping others with answers. The best part is that it is very simple and is free of cost.
-
Hydrogen cracking occurs during friction welding process (or spin welding). Explain why or why not.
Consider high stresses and susceptible microstructures.
-
In welding, the degree of restraint of the workpiece is a mechanical factor of solidification cracking. Explain why.
Observe thermal stress and strain.
-
In submerged-arc welding process, the flux may have moisture content and produce welds of high hydrogen levels (and cracking). Explain why or why not.
Observe agglomerated flux with cellulose.
-
Machine bases are stress releaved to attain dimensional stability after machining. Explain why.
Consider distortion and warping.
-
After welding, stress relieving should not be confused with normalizing or annealing of steels. Explain why.
Observe the critical temperature of steels.
-
A foundry cupola under steel truss (ferritic matrix) induces creep failure. Is it possible? Explain why or why not.
Observe temperature and constant stresses.
-
A root weld bead should never be peened and peening is not permitted on the final pass. Explain why.
Consider work-hardening effect and stress concentration.
-
IN CASE TWO SAME PROPERTIES PIPE LINES WILL BE PASSING THROUGH A WALL & SLAB. YOU SHOULD HAVE PLACE A SUPPORT IN WALL SUPPORT FIXED & SLAB SUPPORT HANGING WHICH TYPE OF SUPPORT IS STRONG WALL OR SLAB
THIS IS USE FULL FOR DISTANCE BETWEEN TWO SUPPORTS CALCULATION

what are the various methods to make a water proof product with less cost
i am doing a electric car project, i face the problem to design the body panelling which is water proof and it cover the motor and electronic components, give some innovative ideas ...
-
Coarse pearlite have poor resistance to fatigue. Explain why.
Observe ferrite plus cementite.
-
A tempered martensite (cubic structure) provides the highest fatigue limit. Explain why.
Consider fully martensitic and the hardness.
