The dimensions of an MS20430AD-4-8 rivet are
1/8 inch in diameter and 1/2 inch long
Which rivet may be used as received without further treatment
2117-T3
How many MS20470 AD-4-6 rivets will be required to attach a 10" X 5" plate, using a single row of rivets, minimum edge distance and 4D spacing
56
A sheet metal repair is to be made using two pieces of 0.040 inch aluminum riveted together. All rivet holes are drilled for 3/32 inch rivets. The length of the rivets to be used will be
1/4 inch
What should be the included angle of a twist drill for soft metals
90 deg
MS20426AD-6-5 indicates a countersunk rivet which has
an overall length of 5/16 inch
Clad aluminum alloys are used in aircraft because they
are less subject to corrosion than uncoated aluminum alloys
Alloy 2117 rivets are heat treated
by the manufacturer and do not require heat treatment before being driven
Rivet pitch is the distance between the
centers of adjacent rivets in the same row
A factor which determines the minimum space between rivets is the
diameter of the rivets being used
Most rivets used in aircraft construction have
dimples
The aluminum alloys used in aircraft construction are usually hardened by which method
heat treatment
Longitudinal (fore and aft) structural members of a semi-monocoque fuselage are called
longerons and stringers
The shop head of a rivet should be
one and one-half times the diameter of the rivet shank
A well designed rivet joint will subject the rivets to
shear loads
What is the minimum edge distance allowed for aluminum alloy single lap sheet splices containing a single row of rivets as compared to a joint with multiple rows, all rivets being equal in diameter
the minimum edge distance for the single row is equal to that for the multiple row
When repairing a small hole on a metal stressed skin, the major consideration in the design of the patch should be
the shear strength of the riveted joint
Shallow scratches in sheet metal may be repaired by
burnishing
Under certain conditions, type A rivets are not used because of their
low strength characteristics
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
lower speed with more pressure applied to the drill
The identifying marks on the heads of aluminum alloy rivets indicate the
specific alloy used in the manufacturer of the rivets
When straightening members made of 2024-T4, you should
straighten cold and reinforce
What is the minimum spacing for a single row of aircraft rivets
three times the diameter of the rivet shank
The general rule for finding the proper rivet diameter is
three times the thickness of the thickest sheet
What is the purpose of refrigerating 2017 and 2024 aluminum alloy rivets after heat treatment
to retard age hardening
What is the minimum edge distance for aircraft rivets
two times the diameter of the rivet shank
