MAE 272- Review 2 Questions with Correct
Answers
Which are non-traditional joining processes? Laser and electron welding
Some guidelines for welding processes are: heat up before welding, and stress relieve
therefore after if necessary
Sand casting of metals is: None
Risers help: None is correct
Hydro and rubber forming can: be cost effective for short-run, shallow sheet metal parts
Knurling performed on a round shaft: all
Guidelines for welding processes include: Heat up parts before welding to reduce
distortions, and stress relieve thereafter if necessary
, Engine blocks for 4-cylinder in-line hybrid engines can be produced in large quantity by:
Advantages of Nesting in sheet metal: assemble two hollow objects into each other lower
tooling costing minimize material waste
Minimum bend radius for AA 7075-O is: Likely to cause cracks inside the bend or 0
Engine blocks for V-6 hybrid engines can be produced in large quantity by: None of the
above
2-piece aluminum beer and soda cans can be produced without: welding
The letter T in AA 6061-T6511 means: annealed or recrystallized grain structures
The frame of an off-the-shelf beach cruiser bicycle is usually made from All of the above
Casting using a sand mold is: appropriate for large and very high precision castings
