Iron
Tin
Nickel
Stainless Steel
Which quenching medium provides the fastest cooling rate?
Oil
Brine
Water
Air
Tempering is done to:
Harden the steel
Reduce brittleness after hardening
Soften aluminum alloys
Increase ductility of copper
Aluminum alloys with the designation T6 mean:
Solution heat treated only

Solution heat treated and naturally aged
Which rivet head code represents universal head rivets commonly used in aircraft?
AN470
AN426
MS20
AD4
In metal bending, the line within the sheet that experiences no compression or tension is:
Bend Allowance
Neutral Axis
Flange Length
Inside Setback
Which of the following correctly defines Bend Allowance (BA)?
Amount added to the sum of flange lengths to obtain flat length
Amount deducted to obtain flat length
Distance between rivet rows
Distance from rivet to sheet edge
In sheet metal work, the K-Factor represents:
Ratio of Neutral Axis position to material thickness
Bend Deduction amount
Rivet head code
Distance between rivet rows
When computing flat layout length, which formula is generally applied?
Flat Length = Leg A + Leg B + Bend Allowance
Flat Length = Leg A + Leg B + Rivet Pitch
Flat Length = Thickness × Neutral Axis
Flat Length = Rivet Pitch × No. of Rivets
