A fourth category, composites, is a non-homogeneous mixture of the other types and therefore is not a basic category. A shaping process changes the geometry of the work material machining or forging. A surface processing operation does not alter the geometry, but instead alters surface of the work painting or plating. Provide an example process for each subclass.

The two subclasses of assembly processes are 1 permanent joining and 2 mechanical fastening. Examples of permanent joining include welding or adhesive bonding. Examples of mechanical fastening include threaded fasteners, such as nuts and bolts, and rivets. Batch production is where groups, lots, or batches or materials or parts are processed together through the manufacturing operations.

All units in the batch are processed at a given station before the group proceeds to the next station. In a medium or low quantity production situation, the same machines are used to produce many types of products.

Whenever a machine switches from one product to another, a changeover occurs. The changeover requires the machine setup to be torn down and set up for the new product. Batch production allows the changeover time 3. A process layout is one where the machinery in a plant is arranged based on the type of process it performs. To produce a product it must visit the departments in the order of the operations that must be performed. This often includes large travel distances within the plant.

A process layout is often used when the product variety is large the operation sequences of products are dissimilar. A product layout is one where the machinery is arranged based on the general flow of the products that will be produced. Travel distance is reduced because products will generally flow to the next machine in the sequence. A product layout works well when all products tend to follow the same sequence of production. A common organizational structure includes the following three manufacturing support departments: 1 manufacturing engineering, 2 production planning and control, and 3 quality control.

Multiple Choice Quiz There are 18 correct answers in the following multiple choice questions some questions have multiple answers that are correct.

To attain a perfect score on the quiz, all correct answers must be given. Each correct answer is worth 1 point. Each omitted answer or wrong answer reduces the score by 1 point, and each additional answer beyond the correct number of answers reduces the score by 1 point.

Percentage score on the quiz is based on the total number of correct answers. What are these categories and give an example of each? The three types of elements are metals e. The noble metals are copper, silver, and gold. Primary bonding is strong bonding between atoms in a material, for example to form a molecule; while secondary bonding is not as strong and is associated with attraction between molecules in the material.

In ionic bonding, atoms of one element give up their outer electron s to the atoms of another element to form complete outer shells. The atoms in a crystalline structure are located at regular and repeating lattice positions in three dimensions; thus, the crystal structure possesses a long-range order which allows a high packing density. The atoms in a noncrystalline structure are randomly positioned in the material, not possessing any repeating, regular pattern.

The common point defects are 1 vacancy - a missing atom in the lattice structure; 2 ion-pair vacancy Schottky defect - a missing pair of ions of opposite charge in a compound; 3 interstitialcy - a distortion in the lattice caused by an extra atom present; and 4 Frenkel defect - an ion is removed from a regular position in the lattice and inserted into an interstitial position not normally occupied by such an ion.

Elastic deformation involves a temporary distortion of the lattice structure that is proportional to the applied stress. Plastic deformation involves a stress of sufficient magnitude to cause a permanent shift in the relative positions of adjacent atoms in the lattice.

Plastic deformation generally involves the mechanism of slip - relative movement of atoms on opposite sides of a plane in the lattice. Grain boundaries block the continued movement of dislocations in the metal during straining. As more dislocations become blocked, the metal becomes more difficult to deform; in effect it becomes stronger.

Materials typically possessing a crystalline structure are metals and ceramics other than glass. Some plastics have a partially crystalline structure. Materials typically having a noncrystalline structure include glass fused silica , rubber, and certain plastics specifically, thermosetting plastics.

Crystalline structures undergo an abrupt volumetric change as they transform from liquid to solid state and vice versa. This is accompanied by an amount of energy called the heat of fusion that must be added to the material during melting or released during solidification. Noncrystalline materials melt and solidify without the abrupt volumetric change and heat of fusion.

Multiple Choice Questions There are 20 correct answers in the following multiple choice questions some questions have multiple answers that are correct. To achieve design function and quality, the material must be strong; for ease of manufacturing, the material should not be strong, in general. Engineering stress divides the load force on the test specimen by the original area; while true stress divides the load by the instantaneous area which decreases as the specimen stretches.

The tensile strength is the maximum load experienced during the tensile test divided by the original area. The yield strength is the stress at which the material begins to plastically deform. It is usually measured as the 0. Because of necking that occurs in the test specimen. Work hardening, also called strain hardening, is the increase in strength that occurs in metals when they are strained. When the material is perfectly plastic and does not strain harden.

In a compression test, the specimen cross-sectional area increases as the test progresses; while in a tensile test, the cross-sectional area decreases. Barreling of the test specimen due to friction at the interfaces with the testing machine platens. What is the test commonly used to determine the strength properties of such materials?

A three-point bending test is commonly used to test the strength of brittle materials. The test provides a measure called the transverse rupture strength for these materials.

Hardness is defined as the resistance to indentation of a material. It is tested by pressing a hard object sphere, diamond point into the test material and measuring the size depth, area of the indentation.

Different hardness tests and scales are required because different materials possess widely differing hardnesses. A test whose measuring range is suited to very hard materials is not sensitive for testing very soft materials. The recrystallization temperature is the temperature at which a metal recrystallizes forms new grains rather than work hardens when deformed. Viscosity is the resistance to flow of a fluid material; the thicker the fluid, the greater the viscosity.

A Newtonian fluid is one for which viscosity is a constant property at a given temperature. Most liquids water, oils are Newtonian fluids. Viscoelasticity refers to the property most commonly exhibited by polymers that defines the strain of the material as a function of stress and temperature over time. It is a combination of viscosity and elasticity. Multiple Choice Quiz There are 15 correct answers in the following multiple choice questions some questions have multiple answers that are correct.

It is the elastic region that is characterized by a proportional relationship between stress and strain. The plastic region is characterized by a power function - the flow curve. Viscosity is the resistance to flow.

Problems Strength and Ductility in Tension 3. During the test the specimen yields under a load of 98, N. This is the 0. Determine a yield strength, b modulus of elasticity, and c tensile strength. During the test the specimen yields under a load of 32, lb. The maximum load is 28, N and the final data point occurred immediately prior to failure.

Determine b yield strength, c modulus of elasticity, and d tensile strength. Solution: a Student exercise. Be sure not to use data after the point at which necking occurred. Determine the strength coefficient and the strain-hardening exponent in the flow curve equation.

Determine the strength coefficient and strain-hardening exponent in the flow curve equation. Without knowing any more about the test, can you estimate the strength coefficient and the strain-hardening exponent in the flow curve equation? Determine the strength coefficient and the strain-hardening exponent for this metal.

Determine a the engineering strain and b the true strain. Does this help to show what is meant by the term true strain? The summation process is an approximation of the integration over the range from 75 to mm in b.

As the interval size is reduced, the summation becomes closer to the integration value. Determine the engineering strain and true strain for this test.

If the metal had been strained in compression, determine the final compressed length of the specimen such that a the engineering strain is equal to the same value as in tension it will be negative value because of compression , and b the true strain would be equal to the same value as in tension again, it will be negative value because of compression.

Note that the answer to part a is an impossible result. True strain is therefore a better measure of strain during plastic deformation. Based on this information, calculate the engineering tensile strength for the metal. Necking begins immediately thereafter.

This is a true stress. TS is defined as an engineering stress. From Problem 3. Therefore, 0. Determine the true stress and true strain at failure. However, it should be noted that these values are associated with the necked portion of the test specimen. Determine the true stress and true strain at this maximum load.

Assuming that the cross section increases uniformly, determine the load required to compress the specimen to a height of a 50 mm and b Determine the force required to achieve this compression, assuming that the cross section increases uniformly. The metal yields 0. At a load of , lb, the height has been reduced to 1. Determine a yield strength and b flow curve parameters strength coefficient and strain-hardening exponent.

Assume that the cross-sectional area increases uniformly during the test. Determine a the shear stress, b shear strain, and c shear modulus, assuming the specimen had not yet yielded.

Hardness 3. He claims that all hardness tests are based on the same principle as the Brinell test, which is that hardness is always measured as the applied load divided by the area of the impressions made by an indentor. Solution: a No, the claim is not correct.
