Activity 5.6 Physical Property Analysis Introduction What do you need to know about a product before it is built? Would you need to know its volume, surface area, or weight? Would the product weigh less if it were made of aluminum or mild steel? What about copper, brass, or cast iron? How could this information impact the product design? How can you find the properties of a product before it is built? You can calculate them mathematically, providing you have the material specifications, but it will take time. In today’s busy, fast-paced world, engineers use solid modeling software programs to speed up the calculating process. However, the user of the software must understand what the software is doing in order to estimate the answers and to be able to recognize a possible error. Equipment Engineering notebook Pencil Computer with 3D CAD solid modeling software Calculator Procedure In this activity you will calculate the volume of a part and the surface area; you will look up the density of the material and then calculate the mass. Next, you will check your work using a 3D solid modeling software program. To earn full credit please remember to show all work by either: a. Neatly typing your work into the appropriate places throughout the activity. b. Attaching a picture of your work at the bottom and typing “see attached work” in the appropriate places. Make sure to neatly label your work. Add in screen shots for each object that includes the center of mass and your property analysis. © 2012 Project Lead The Way, Inc.
