How may acoustic designers alter the design of a room, which was previously used for music performances, into a room now to be used for spoken word performances? Use annotated diagrams for your response. For the answer please include the different materials used in the different settings. I.e what designs and materials will be used for a music room vs a speech room.

Day 1: Why do engineers use prototypes in the engineering design process? Day 2: What are you learning about the mechanical praperties of the materials you are using to construct your prototype? Day 3: What successess and challenges have you experienced during the prototyping phase of the EDP?

In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?

Project 7: Decide whether you choose an amorphous or crystalline polymer for the following products and/or applications and justify your answer: A. Graphite: B. Tempered glass: C. High thermal conductivity ceramics: D. Hot coffee cups Briefly explain why amorphous polymers are transparent, while predominantly crystalline polymers appear opaque or translucent.

Two students decided to print a prototype for a gear. Student A use layer thickness of .1 mm and an infill density of 25%. Student B use a layer thickness of 0.07 mm and an infill density of 45%. Which student will take less time to print the gear? Select one: Stu nt since the ckness of layer is smaller and the infill density is higher. O We can't decide which process takes less time O Student A since the thickness of the layer is larger and the infill density is lower. Student B because thickness is higher than B and the infill density has no effect on the process speed. Student A because thickness is higher than B and the infill density has no effect on the process speed.

Hi i need help on what is the answer for this problems? Below is the questions and no plagiarism please? And can it be in type form not picture and lastly minimum of 5 sentences each question. Thank you

Pls answer asap. Thanks sir!

Please make sure to display your thought process? It is imperative to be able to follow how the answer was deduced. Please be as thorough as possible. Please address all parts of this question as they are all part and critical to answering this question correctly. Please show good integrity when answering the question: Strain-rate, temperature, pressure, and aging time all affect the stress/strain behavior of polymers. Draw a stress-strain curve below for a typical ductile polymer. Clearly label the yield point and the ultimate tensile strength. Using this curve draw two new curves corresponding to same polymer but now tested at: 1) an increase in temperature and 2) an increase in strain rate. Explain what happens to the tensile behavior after: a) a prolong time of aging time is increased and b) when the tensile tests are conducted under super imposed hydrostatic compression

Show the typical Stress versus Strain curve for the following materials, and define the materials properties "The stress-strain curve can be used to read off the structural load ability of materials. For many materials, including metals, their loading bearing capability is one of the most important material properties". by reference to the diagram: a) Hammer head is made from hardened tool steel b) Smelter is made from refractory ceramic c) Cable is made from pure copper d) Box is made from polypropylene

In 1907 a janitor called Murray Spangler put together a pillowcase. a fan, an old biscuit tin and a broom handle. It was the world's first vacuum cleaner_ One year later he sold his patented idea to William Hoover whose company wont on to dominate the vacuum cleaner market for decades. especially in its United States homeland. Yet between 2002 and 2005 Hoover's market share dropped from 36 per cent to 13.5 per cent, Why? Because a futuristic looking and comparatively expensive rival product, the Dyson vacuum cleaner, had jumped from nothing to over 20 per cent of the market. In fact, the Dyson produce dales back to 1978 when James Dyson noticed how the air filter in the sprayfnishing room of a company when; he had been working was constantly clogging with powder particles (just like a vacuum cleaner bag clogs with dust). So he designed and built an industrial cyclone lower, which removed the powder particles by exerting centrifugal forces. Thy question intriguing him was, could the…

These are some characteristics of advanced ceramic materialsChoose an option A) Its composition is not exact, having a great variety of minerals in its raw materials.B) They need a sintering process for their manufacture.C) Sintering must be done with compacted raw materials in powder form and must reach the melting temperature of all its components.D) Its particles must have a micrometric diameter to facilitate sintering.E) What allows them to have the final solid form is the vitreous league.F) They are fragile and not very resistant to changes in temperature

What are some of the ways for improving the accuracy of FEA for 3D printed components? Select all that applies. A) Explicit modeling of the component B Analyzing the model as an assembly Using Non linear material model Using orthotropic material model

Q1: What are the two main types of characterization of smart materials? Using as few words as possible, explain the difference between them. Moreover, show that the idea of characterization is true by giving a working example per each type.

Task 1 The company is interested in expanding its production capability into ceramic based products. You have been asked to identify typical products manufactured using selected ceramic processes and then describe how the properties of the ceramic make this a suitable process for the product. Briefly describe the process and then examine which types of products which can be manufactured using this process. Then describe the properties that make the ceramic and process suitable for that application. · Ceramic Sintering · Ceramic Hot Pressing · Chemical Vapour Deposition · Reaction Bonding process
