In this activity you will practice taking linear measurements using a standard ruler marked in US Customary units and correctly recording the measurements to reflect the precision of the measurement.
Conclusion Questions1. When you look at a drawing, how do you know if you are looking at U S Customary or SI measurements? Why is it important for an engineer to know this piece of information?
When you are looking at a picture with measurements then you can find out if it is US or SI measurements by the symbol or sign that comes after the number. It is important for an engineer to know about measurements so he can transfer the dimensions of a building from US to SI measurements if this person is not from the US. Activity 3.1a SI MeasurementIn this activity you will practice taking linear using SI measurements with a metric ruler and correctly recording the measurements to reflect the precision of the measurement.
Conclusion Questions1. Explain the meaning of significant digits (or significant figures) in measurement.
A significant figure is each of the digits of a number that are used to express it to the required degree of accuracy starting from the nonzero digit. 2. Why is the metric system used instead of the US customary system, and vice versa, in various parts of the world? The metric system is used instead of the U.S customary system in other parts of the world because they are not part of the U.S and this is what they are using. Activity 2.5 Sketching PracticeIn this activity you will apply the skills that you learned earlier in this lesson to more complex objects.
Conclusion Questions1. What is a technical sketch? What is an artistic sketch? How are the two similar and how are they different?
A technical sketch is an important sketch made for Engineers so they can know how big the building will be able to be built there. An artistic sketch is like a drawing or painting that can be made for fun but a technical is important. 2. How do you envision applying your sketching skills in other classes? To be honest, I think that I did not like this unit but I learned a lot about sketching so that the next time I take a class that has sketching I will enjoy it and have fun. 3. How do you envision applying your sketching skills in college? I can be able to sketch if I decide to become an Engineer then college courses will be a little easier for me since I have some knowledge about it. 4. How would you teach sketching to a student next year? I would teach sketching to a student next year by saying you will be confused and become irritated at times but if you keep trying harder it will become easier. |
In this activity you will design and build a box from a flat sheet of transparency film. You will then use your glass box to help you sketch orthogonal projections of an object and create multi-view drawings.
Conclusion Questions
1. How do you determine the orientation of orthogonal projections in a multi-view drawing?
1st you have to identify the front of the 3d figure and then you go on from there identifying everything else 2. How would you describe the geometric relationship that exists between the adjacent views of a multi-view drawing? They all have the same number and size of edges and sides and having some of the same measurements such as width, depth,height 3. Why is it important to lay out a multi-view sketch with points and construction lines before drawing object lines? This is important so you can have an idea about where you are going to start and how much the measurements are and it also helps you sketch easier |
Conclusion Questions1. What is a vanishing point?
A vanishing point is the point at which receding parallel lines viewed in perspective appear to converge 2. Aside from the number of vanishing points, what is the difference between a one-point, two-point, and three-point perspective sketch? The 1st point perspective is made by one vanishing point is identified on the horizon line. The two point perspective is the most common perspective drawing. The three point perspective is called the birds eye view. 3. How does a perspective drawing differ from an isometric drawing of the same object? When would you use a perspective view in lieu of an isometric drawing The differences that I think are between isometric and perspective drawings are that isometric is easier and uses isometric paper but perspective is harder and used graph paper and it also has 3 points of perspective. |
Activity 1.7 What Is It?Assume that you are an engineer that has developed a preliminary design for an important problem. Write and present an explanation and evaluation of your design.
Conclusion Questions
1. Why is it important for engineers to be creative and think outside the box?
It is important for engineers to be creative and think out the box to make better and more amazing designs to help the world in other types of ways. 2. What other characteristics do you believe engineers should possess in order to be successful problem solvers? Another important characteristic that engineers should have is being able to work in groups so they can have more brilliant ideas together and have help from each other. |

Activity 1.6 Discover EngineeringIn this activity you will investigate the four major disciplines of engineering and consider their impact on you and the world.
|
Activity 1.6 Conclusion Questions
1. What is it about engineering that is common to all disciplines of engineering? That is, what makes an engineer an engineer regardless of the work one does An Engineering is basically a person who designs something. However, different types of engineers design different things 2. Why do you think engineering has been called the stealth profession? (Hint: there are many Internet resources that address this question.) I think that engineering is called the stealth profession because nobody really knows what the engineers do. 3. How is an engineer different from a scientist? An engineer uses science and math to design things such as buildings, etc., and a scientist uses science and math to create chemical equations. 4. What interpersonal characteristics do you think are important to the success of an engineer of any discipline? The interpersonal characteristics that I think are important to the success of an engineer is getting along with others. If they don't work together work will be hard but if they work together they can brainstorm a lot of ideas and have more helpers. |
