Day 13 Intro to Engineering Allen Sam 6-28-18 Activity 5.6a Aluminum Object Example 1 1.       What is the volume of the part? A.      1.875 in.³ B.      1.125 in.³ C.     1.375 in.³ D.     2.125 in.³ c.1.375                  2.                                                       What is the density of aluminum in grams per cubic centimeter? (This may require research. Be sure to document your source.)  2.700g/cm^3 3.              ...

Day 12  Intro to Engineering Allen Sam 6-27-18 Activities 5.5a and 5.5b 5.5a   Conclusion:  1.        What 3D CAD functions could be used to create a wire coat hanger? I would use the sweep, loft, and revolve functions of CAD to create the coat hanger from the front view and a side view. Activity 5.5b \ Conclusion:  1.    What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer. I would use the revolve tool to create the baseball bat because the baseball bat is cylindrical     2.    How does a 3D CAD solid model program display the progression of work involved in creating a model? You can see progression of the work of a project by showing the constraints and CAD features that were used. 3.    If a mistake is made, how does the user...

Day 11 Intro to Engineering Allen Sam 6-26-18 Activities 5.3, 5.4 Activity 5.3 Conclusion 1.       How can you use density to identify a material? You can figure out a certain material by comparing it it an index that has the densities of certain materials 2.       What are limitations of the calculated and indirect volume measurement? If the object doesn't fit within a measurable container, the volume can't be determined through indirect measurement 3.       Explain the difference between weight and mass. Mass is the amount of matter packed within an object but weight is the amount of force it exerts of mass considering the gravity's existence. Activity 5.4

Day 10  Intro to Engineering Allen Sam 6-25-18 Activities 5.1, 5.2a, and 5.2b Activity 5.1 Conclusion: 1.        What is the difference between a circle and an ellipse?   A circle is an ellipse but with an equal major and minor axis. An ellipse will have two focal points but in a circle the center is the focal point. 2.        What is the difference between an inscribed and a circumscribed shape?   An inscribed shape is a shape when it is in another shape. A circumscribed shape is a shape that surrounds another shape. 3.        Why is it impossible for a triangle to contain a 180° angle?   It is impossible for a triangle to have a 180 degree angle because This causes the other two distances in the triangle to match at the tip with interior angles of 0 degree. This forms a line instead of a triangle. 4.   ...
