different casting process, discuss each process and describe the most ideal method of making

Grey cast iron, which contains between 2.5 and 4% carbon, has all or most of its carbon is uncombined in forms graphite flakes when it cools and solidifies from its molten state. True or false.

Knowing that the allowable normal stress for the steel used is 24 ksi, select the most economical S-shape beam to support the loading shown.

For the process shown in the schematic below, which of the statements is/are incorrect? Feed hopper Feed hopper Plastic pellets Mold cavity Mold Nozzle Spreader Heating chamber Ram Hydraulic pressure Turning screw Barrel Heaters Shaping die Molten plastic Extrudate Select one or more: a. The process can only work with thermoplastics and not with thermosets due to the thermal processing requirements Tubing and pipes Sheet and film Structural parts b. The feedstock has to be molten or liquid monomer, the temperature of which will constantly be held above the melting temperature c. This process is best suited for the large volume production of tubes, bars and beams due to the nature of the extrusion process d. To release the part, the process typically involves the mould sections opening and the ejector pins pushing the object out of the mould De. The mould cavity region is usually temperature controlled so that at the point of injection it is heated and then gradually cooled down until…
