Day 8 Intro to Engineering Allen Sam 6-20-18 Activity 4.1c 1.        Consider the data that you have graphed and answer the following. a.        Would you expect that this data is linear; that is, if you were to measure the mass of other pieces with more than six cubes or fewer than four cubes, would the points fall on a straight line on the graph? Explain your answer. I expected the data to be linear because the cubes are similar enough to be the same mass. On a graph, they should fall in the same line because the weight and number of cubes should be proportional. b.        If you were to sketch a line-of-best fit, what would be a reasonable y-intercept. That is, where would the line-of-best fit cross the vertical axis? Explain your answer. It should cross the vertical axis at (0,0) because having no cubes should result on 0 mass. c.    ...

Day 7 Intro to Engineering Allen Sam 6-19-18 Activity 4.1a Conclusion 1.       Why is it so important for a designer to think of multiple solutions to a design problem? It is important for a designer to think of multiple solutions because the design for solving the problem ma not be practical of too costly.    2.       What steps did you take to determine the exact number of possible combinations for each set of cubes? I looked at a basic shape and added one cube around every possible block to get a new combination.    3.       Why is it important to sketch your ideas on paper and sign and date the document? It is important because you need to prove that the sketch was your own work. Activity 4.1b 1. design 1 design 2 2. I think I liked design 2 better because it is more complex than the first one. Also, the first design has too many pie...

Day 6 Intro to Engineering Allen Sam 6-18-18 Activity 3.4 Conclusion 1.     Why is placement of your dimensions so important?  The placement of a dimension determines what side a measurement goes to, so making sure the placements of the measurements represent the dimension of the right sides is important. 2.     Why do designers need to fully dimension a part?  Engineers need to fully dimension a part for builders to know all the shapes and sizes of it. 3.     What does it mean when a sketch is over dimensioned ?  Over dimensioned means that a sketch has too many measurements that are not needed because they are implicitly there already. Activity 3.5 1.        How can statistics of a product’s dimensions be used to assess the quality of the product? The statistics can determine whether a product is accurate or not...

Day 5 Intro to Engineering Allen Sam 6-15-18 Activity 3.1a Linear Measurement SI Record the length of the rectangles shown in the following figure using SI units and the correct number of significant figures. Include the units in your answers. Distance Measurement 1. A  0.4cm 2. B  1.9cm 3. C  3.75cm 4. D  6.25cm 5. E  7.3cm Calculate each of the following lengths and record the answer using appropriate significant digits and the correct units. Show all calculations. 6.       What is the difference in the length of rectangles A and C? 3.75cm - 0.4cm=  3.35cm 7.       What is the difference in the length of rectangles B and E? 7.3-1.9=5.4cm   11.         What type of pictorial is shown in number ...
