Activity 2.2.1 Product Analysis - Principles of Engineering
Activity 2.2.1 Product Analysis5095240000IntroductionWhat materials should engineers consider when designing a shoe? The shoe must meet your performance expectations and must be durable enough for everyday demand. While materials possess similarities to one another, their differences are equally important as engineers search for the correct material to create a product. When selecting materials, engineers must ask the following questions:Will extreme conditions affect the material? Will these conditions cause the material to fail, and if not, how safely will the material carry the load? How will the material respond if its temperature is drastically changed? Will the material remain as strong as it was prior to being formed? Will the material corrode when exposed to extreme conditions?When engineers can’t find a material that provides the desired traits, they invent new materials by combining several existing materials.Material selection for products requires engineers to consider material properties against anticipated use. Engineers must sometimes find an alternative material for a part in their design for many reasons, including environmental issues, cost issues, or safety issues.Equipment 3D modeling softwareEngineering notebookDigital scaleNailMeasuring device – dial caliper, ruler, micrometer, etc.ProcedureCategorizing materials and identifying their properties is an essential skill in the everyday life of an engineer. Part 1 Analysis:Individually brainstorm a list of 6 common products found in your backpack, classroom, or at home that consist of at least two parts. These products may be items such as a pen, lightbulb, stapler, backpack, etc. Record your list of products below.a. b. c.d. e. f.Identify two products from your brainstorming list to bring use or bring to the next class meeting. Obtain teacher approval of products.ProductTeacher Approval#1:#2:Examine the functions and properties of both product #1 and product #2.Illustrate and describe product #1. Include detailed information relating to function, operating procedure, cost, and manufacturing origin.IllustrationDescription1.2.3. 4.Illustrate and describe product #2. Include detailed information relating to function, operating procedure, cost, and manufacturing origin.IllustrationDescription1.2.3. 4.It may be necessary to disassemble your product in order to proceed with this activity. See instructor before proceeding.Select one component from each product to investigate further.Product #1 Component Product #2 Component Product #1 Component #1 ______________________________TestDescriptionResultsContinuity Test:Use a multimeter with a built-in continuity tester or a simple circuit consisting of a power source and light to check for the component’s ability to conduct electricity.Ferrous Metal TestPass a magnet over the component.Hardness:Use a nail to attempt to scratch the surface of the component. Weight:Use a digital scale to weigh the component.Mass:Mass = weight / gravitySurface Area:Use a measuring device and calculator to sum all of the areas that cover the surface of the component.Hand Flexure Test:Use only your hands and attempt to bend the component. Does the component permanently deform?Product #2 Component #1 ______________________________TestDescriptionResultsContinuity Test:Use a multimeter with a built-in continuity tester or a simple circuit consisting of a power source and light to check for the component’s ability to conduct electricity.Ferrous Metal TestPass a magnet over the component.Hardness:Use a nail to attempt to scratch the surface of the component.
