What are the characteristics of the element iron that make it good for seeding?  Please include the chemical properties of powdered iron in your answer

Why would I elect to use grey cast iron rather than a low-carbon steel? Why would I want austenitic rather than ferritic steel?  Why is it that polymers are a 100 times stiffer than bulk polymers or a polymer fibers. Why are they so much stiffer and stronger than bulk polymers? What explains that?

Your die setter brings you a print of a cylinder with a 2 inch outside diameter and a 1.75 inch inside diameter. The cylinder is to be molded of iron powder with a green density of 6.8 g/cc. The apparent density of the powder is 2.9 g/cc. What is the die fill if the green part is to have a height of 2.5 inches? (show your work)

May I have help with this please?

I need help answering this question, please To select a material for an application, it is necessary to evaluate whether its chemical and mechanical structure can be applied to a specific function and whether its properties will meet the required demands of the applied product. One way to identify these characteristics is to understand the types of deformations that materials can undergo. Describe the differences between elastic deformation and plastic deformation in polymers, and how these concepts influence the mechanical properties of polymeric materials. Then, provide examples of practical situations where each type of deformation can be observed.

The figure shown below (Fig. 2) is a schematic representation of a scissor jack in two different positions. The maximum load that this mechanism must withstand is 800 kg. 4 are proposed different materials to make the jack arms and spindle. The mechanical properties and some Physical characteristics of each material are shown in Table 1. a) Based on the properties of each material and the cross section of the arms and the screw, Propose what would be the most suitable material for its manufacture. The length of each arm is 150 mm. The stress on the arms and the spindle must not exceed the yield strength of the material selected for neither of the two analysis positions. b) Using the mechanical properties of the material you selected, calculate the change in dimension that the arms and the spindle of the jack were tested for the two analysis positions. The length of the spindle is 280 mm.
