M6 PRACTICE QUIZ

Since heat is used as curing agent, these resins may tend to run off of any vertical or near vertical surface before they have a chance to cure. "They run like water."

Iron, or any alloy containing iron.

Is a reaction of two different types of molecules when reactive groups are brought together.

Titanium and titanium alloys can only be welded under

Rivet diameter

40/100 is equal to

The material is heated to a specified temperature and held there for a specified time.

A flush rivet with a very small flush head and the head of the rivet is slightly arced and has a special head mark

The thickness of the clad layers is about

Sheets made of alloys are with a thin layer of pure aluminium on both sides as a means of corrosion protection.

The ratio of stress to strain within the proportional limit of a material in tension or compression.

The maximum stress that can be applied to a material without permanent deformation of the material.

Is not brittle

Fastening material has been developed, which deforms its back when a tension load applied at the front

When determining the length of a fastener for installation, the combined thickness of the material to be joined must be known. This measurement is known as

Rivet Material: what is the code of raised cross

Rivet Material: What is the head mark of monel

Rivet Material: What is the code of 5056 Aluminium Alloy

AD rivets are identified by a small dimple in the centre of their head.

They are identified by two raised dashes on their heads and they are so called icebox rivets.

These rivets are identified by a raised cross on their head.

The property of a metal which allows it to be deformed without breaking.

When screwed into a hole of the correct diameter they form their own thread. The screw head may be slotted or cross recessed.

In cable denomination what is the number of wires in one strand

HI-LOCK COLLARS: What is the colour of collars with the supplier part number of "HL 279"

Bearings typically have to deal with two kinds of loading

This is basically a finer version of the Whitworth thread form. The smaller thread provides a finer form of adjustment and greater resistance to vibration in all fastening devices.

Is an engineering component which when deflected by a force tends to return to its unloaded shape. Ideally the energy input to cause the deflection is usefully recovered.

These inserts are manufactured from round wire which is converted into a diamond-shaped cross-section having a tolerance of .0005mm (0.0002 in) across the flats.

. It is also important to ensure that the lubricant is clean since contaminants tend to get trapped in the race groove, which ultimately limit performance and bearing life.

S uniformly distributed over a certain area, the force per unit of area, usually expressed in pounds per square inch, is called the

These cables consists of four twisted AWG 24 wire with a common shield.

Airbus Customer number

The stress at which a material in tension, compression or shear will fracture.

Is made from small strands of molten silica glass and than spun together and woven into cloth.

What is the standard thread of ANC and ANF (American National Coarse and Fine)

The hole is bigger than shank

The shank is bigger than the hole

Fit in any structure or same size

What is the temper designation of annealed

What is the temper designation of solution annealed

Applicable for steel components, which are hardened and have to be softened for mechanical processing.

Occurs between two materials that come into contact. The metals may be similar or dissimilar or in some cases one of the parts may be nonmetallic.

In integral fuel tanks is caused by bacteria, fungi or yeast in unclean kerosene-type jet engine fuel.

The screw which has a deeper thread cut into its surface will have fewer threads per inch (of its axial length) and is said to have a coarser pitch than the shallow thread.

Is the sheathing of wires and cables with an electrically conductive material in order to prevent electromagnetic fields from either entering or escaping from wires and cables.

They can be used to record and control the temperature of a repair.

A solid rivet is formed by deformation of the shank.

Has a total of nine atoms. One is at each corner of the cube and one in the centre.

Is a rigid body in which the constituent particles are arranged in a repeating pattern.

Small surface damage such as scratches, nicks or corrosion causes a change of stress distribution of the component, risk of cracking would be the result.

Occurs when low-alloyed steels are deformed chipless in the cold state.

Is when the separation of plies occurs in a multi-laminate material. This can be caused by the material being hit, or when there is a resin failure for any other reason.

Any wetting with acidic fluids or mordants can lead to

When heated,resin becomes a plastic. After cooling, the resin sets and hardens in a given form. Hardening is reversible.

The number of prepreg layers and their orientation determines what

Diamond cone penetrators is part of

A commonly-used rule of thumb for selecting the rivet size is to choose a rivet

They are area-measured-materials which cross rectangularly with warp threads and filling threads

When the core is bonded between two thin-face sheets, it provides a rigid, lightweight component. This type of construction is known as

Denominates fibres which are combined to fibre bundles in large amount without any twist and nearly parallel. Commomny they consist out of 60 threads which are made out of 200 elemental fibres.

Pure aluminum

Strain hardening at heat treatment.

Rapid cooling of material after heating (soft anealing) in a liquid to retain strength properties gained

The process on high alloy steels increases the yield strength by temperature depending solution of aluminium atoms within the iron-crystal.

The relations between external forces applied to an elastic body and the deformations and internal stresses resulting from those applied forces.

One of the most common methods today is to crimp these elements onto a wire by means of a special crimping tool. This procedure is also called
