n automobile accessory designer, you must choose between two materials for building bulletproof windows. You put each substance to the test by shooting one bullet at it. You discovered that the first glass causes bullets to b

Your supervisors at A&L Engineering have tasked you with evaluating the durability of three common materials used in the design of cell phone cases. For each material type, you have been asked to determine the force of impact of a phone dropped from a set height above the ground. Using the mass of each case and the collision time, determine the force of impact on each case material and determine which case material offers the most protection. To facilitate your analysis, you have been provided with specifications for case materials in the table below. However, you may also use your own figures for the mass of phones and test case materials. If you do use a different figure, be sure to make that clear in your analysis. As you use this data, ensure that you have made the necessary SI unit conversions: Test Material   Mass                              Collision TimePhone only (no case) 6.2 oz.                       0.01 secondsSilicone 1.7 oz.                                   0.05…

The understanding and modification of the structure and properties of materials to improve the performance and processing of the material is called

When answering  the following questions , ensure that you explain in terms of both the microscopic and macroscopic structure of the materials. A) polymer - explain the difference in structure between a thermoplastic and thermoset material and explain how the structure accounts for the key generic properties of those polymers. B) composite material - for a particular composite and a fibre reinforce composite , explain the difference in structure and whst structual features dictate the properties of the material.
