Cast iron just like steel has wide applications. It is an alloy with carbon content in excess of about 2%C (usually between 2.5 and 4.3%C) and Si content in excess of 0.5%. The microstructure of cast iron after solidification influences the final properties of the casting From the iron carbon phase diagram above answer the following questions: a) Calculate the volume fraction of ledeburite (eutectic component) present in the alloy containing 3%C after solidification under: i) equilibrium conditions ii) fully...

6. Estimate the angular acceleration of the wheels on your car in a typical start from zero to 30 m/s. This does not mean some wild, unjustified number of radians/s2. It does mean making at least two numerical estimates and using them in at least 3 equations, all of which must be shown to get credit on this one. If you need some hints, check the Discussion section on Canvas 7. The maximum pressure Portland cement concrete can withstand...

1.The minimum wavelength and the minimum wave length for visible light is about 0.4 um and 0.7 um, respectively . Assume that the velocity of light is a constant of 3.0x10^8 m/s and Planck's constant is 4.13x10^-15 eV-s. What kind of material will appear colored? (a)The material with band gap of 1.0eV (b)The material with band gap of 2.0eV (c)The material with band gap of 3.2eV (d)The material with band gap of 3.5eV 2.Which kind of material is most likely...

please answer question 2,3,4
A critical feature of steel is that a considerable amount of carbon can be dissolved in the austenite, phase, (up to 2.14 w/o at 1147"C), whereas carbon is essentially insoluble in ferrite, Cooling from point d to e, just above the eutectoid but still in the an increased fraction of the +y region, will produce phase and a microstructure similar to that shown: the particles precinitates out in the form af an intermetallic.compound called iron-carbide...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
