Sheet Metal Test 12/7

8105. When comparing the machining techniques for stainless steel sheet material to those for aluminum alloy sheet, it is normally considered good practice to drill the stainless steel at a

• A-higher speed with less pressure applied to the drill.

• B-lower speed with more pressure applied to the drill.

• C-lower speed with less pressure applied to the drill.

8108. What is the minimum edge distance for aircraft rivets ?

• A-Two times the diameter of the rivet shank.

• B- Two times the diameter of the rivet head.

• C - Three times the diameter of the rivet shank.

8110. What is the minimum spacing for a single row of aircraft rivets ?

• A- times the diameter of the rivet shank.

• B- Three times the length of the rivet shank

• C-Three times the diameter of the rivet shank .

8113. What is one of the determining factors which permits machine countersinking when flush riveting?

• A- Thickness of the material and rivet diameter are th same .

• B- Thickness of the material is less than the thickness of the rivet head.

• C Thickness of the material is greater than the thickness of the rivet head.

8114. When repairing a small hole on a metal stressed skin, the major consideration in the design of the patch should be

• A- the shear strength of the riveted joint .

• B-to use rivet spacing similar to a seam in the skin.

• C-that the bond between the patch and the skin is

Which procedure is correct when using a reamer to finish a drilled hole to the correct size?

• A-Turn the reamer in the cutting direction when enlarging the hole and in the opposite direction to remove from the hole.

• B-Turn the reamer only in the cutting direction.

• C-Apply considerable pressure on the reamer when starting the cut and reduce the pressure when finishing the cut.

8118. Clad aluminum alloys are used in aircraft because they

• A-are naturally corrosion resistant, so they do not require corrosion resistant materials for protection.

• B-have surface layers of pure aluminum or aluminum alloy bonded to the core material to inhibit corrosion .

• C - are highly corrosion resistant because an oxide film forms on their surfaces upon contact with air.

8121. A factor which determines the minimum space between rivets is the

• A - length of the rivets being used .

• B - diameter of the rivets being used .

• C - thickness of the material being

8126. Rivet gauge, or transverse pitch is the distance between the

• A-centers of rivets in adjacent rows .

• B-centers of adjacent rivets in the same row.

• C - 1 heads of rivets in the same row.

8127. Rivet pitch is the distance between the

• A-centers of rivets in adjacent rows.

• B- centers of adjacent rivets in the same row

• C-heads of rivets in the same row.
