Study Notes
Organizational Structure
- Functional organization: a sound basis for balancing human resources and skills
- Matrix organization: can lead to a "dual boss" phenomenon
- Matrix organization: advantage is better utilization of resources
- Matrix organization: disadvantage is dual accountability of personnel
- Projectized organization: advantage is efficient use of technical personnel
- Projectized organization: disadvantage is insecurity regarding future job assignments
- Functional organization: advantage is efficient use of technical personnel
- Functional organization: disadvantage is weak project authority
Morris Life Cycle Model
- A project is divided into 4 stages to be performed in sequence
- First stage is planning and design
Risk Management
- Risk management: refers to techniques used to minimize or mitigate risk consequences
- Risk absorption: involves absorbing the risk in the project
- Risk elimination: involves eliminating the risk
- Risk reduction: involves reducing the risk
- Risk sharing: involves sharing the risk with others
- Buying insurance: a form of risk sharing
Engineering Materials
- Atoms are considered the "building blocks" for engineering materials
- Major classes of engineering materials: metals, ceramics, polymers, semiconductors, and composites
- Ferromagnetic materials: behave like iron when placed in a magnetic field
- Metal matrix composites: metals reinforced by ceramics or other materials in fiber form
- Polymer: a combination of one or more metals with a nonmetallic element
- Composite: a combination of two or more materials that has properties the components do not have by themselves
- Periodic Table: a reference sheet for the elements that can be used to form engineering materials
Material Properties
- Melting point: the physical property of a material that refers to the point at which a material liquefies on heating or solidifies on cooling
- Hardness: a mechanical property of a material that refers to the resistance to plastic deformation
- Nil ductility temperature: the temperature at which the toughness of the material drops below some predetermined value
- Endurance limit or fatigue strength: the stress level below which a material can withstand a large number of stress cycles without failing
Polymer Production
- Copolymerization: a polymer production process that involves forming a polymer chain containing two different monomers
- Polyamide: a generic name of a class of polymer which is commercially known as "nylon"
Steel and Alloying
- Pickling: the use of acids to remove oxides and scale on hot-worked steels
- Molybdenum: used to increase dynamic and high-temperature strength and hardness in steel alloying
- Steel identification: prefix "E" means composition varies from normal limits
- Steel identification: prefix "B" means it is made in an electric furnace
- Steel identification: suffix "B" means it is steel with boron as an alloying element
- Stainless prefix: a steel cannot qualify for stainless prefix until it has at least 10% of chromium
