Materials Engineering

Material engineering is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. Materials engineering incorporates elements of applied physics and chemistry.

In recent years, there has been significant media attention focused on nanoscience and nanotechnology. Material science is now becoming more widely recognized as a specific and unique field. As a result of then, material engineering has become a more reputable degree in universities. Many of the most pressing scientific problems that are currently faced today are due to the limitations of the materials that are currently available and as a result, breakthrough in this field is likely to have a significant impact on the future of human technology.

The basis of material science involves relating the desired properties and relative performance of a material in a certain application to the structure of the atoms and phases in that material. Major determinants of the structure of a material and thus of its properties are its constituent chemical elements and the way in which it has been processed into its final form.

Material science encompasses various classes of material which may constitute a separate field. Industrial applications of materials science include material design, cost-benefit trade-offs in industrial production of materials, processing techniques and analytical techniques. Aside from material characterization, a material engineer also deals with the extraction of materials and their conversion into useful forms.

Design of the internal fixation plate composite material

Task: Bioengineer needs to design a plate for the internal fixation of fractures using the Voigt's model. The plate should be made out of composite material containing carbon fibres and PMMA (Poly(methyl methacrylate)). The engineer has tabulated data about material properties (Young's modulus E, mass density ρ and ultimate ten

Partial Pressure of Reactant from Flow Rate

I am trying to find the partial pressure of ethylene for this equation. The reaction is ethylene polymerization, i.e., ethylene to products which is first order in partial pressure of ethylene: The flow rate of 5% ethylene/He (balance) in gas phase is 50 mL/min for a small laboratory downward reactor tube made up of quartz.

Concentration of fluid

The following growth equation was derived for color-dyed rock candy: (see the attachment for the equation), where R is growth rate in units (mm/min) and C is concentration of dye in parts per million (ppm). Growth rate data was collected for the following concentrations: (see the attachment for the table) a) What are the nu

Calculating heat energy and work to dry wood on a steam heated hot plate

Please see the attached file for the fully formatted problem(s). Problem 1: > A piece of wood is 2ft x 2ft x 0.25 ft ----- the hot plate is also 2ft x 2ft square > A wet piece of wood is placed on a steam heated hot plate ---- the dry weight of the wood is 10 lbs ----- the weight of the water in the wood is

Heat Transfer : Steam and Aluminum

1: Steam at 100°C is passed into a condenser at a rate of 500 kg/h and leaves as water at 60°C. If the condenser is supplied with cooling water which enters at 20°C and leaves at 40°C, calculate: a) how much heat per hour is extracted from the steam. b) how much cooling water is needed per hour. 2: A cupola furnace is c

1. A propane tank is located 100 m away from the nearest buildings. The fragility to explosion can be expressed by p = 0 for I < 0.7 MPa ? s p = aI for 0.7 < I < 1.3 MPa ? s p = 1 for I > 1.3 MPa ? s Accounting for various release and ignition scenarios, including uncertainties, the estimated probability distributio

Rate of Heat Loss through a Window

The two surfaces of a window are maintained at specific temperatures. The rate of heat loss through the window and the inner surface temperature are to be determined. Properties: The thermal conuctivity of the glass is given to be k=0.78 W/m·C. The area of the window and the individual resistances are A=(1.2m) x (2m) = 2.4 m
