Continuity 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.
no
Ferrous Metal Test
Pass a magnet over the component.
no
Hardness
Use a nail to attempt to scratch the surface of the component.
Yes with force
Weight
Use a digital scale to weigh the component.
2.5g
Volume
Submerge the component in a container with a predetermined measurable amount of water (graduated cylinder, beaker, etc.). If the component is buoyant, use a paperclip to keep the object submerged during testing. Measure the increased volume of the water due to the component being submerged in the container.
When first submerged did not sink added paper clip that changed volume by 1 with pencil changed by two volume of pencil is 1
Mass
Mass = weight / gravity
2.5
Density
Density = mass / volume
2.5
Surface Area
Use a measuring device and calculator to sum all of the areas that cover the surface of the component.
10.857
Hand Flexure Test
Use only your hands and attempt to bend the component. Does the component permanently deform?
no
1. How does design affect material selection?
2. What other factors affect material selection other than design?
3. What properties of materials are important to understand before selecting materials for production?
4. What is liability? What are the liability issues, if any, related to the materials for each product that your team selected?
