Activity 5.1 Calculating Properties of Shapes


Activity 5.1 Calculating Properties of Shapes





Conclusion
1.      What is the difference between a circle and an ellipse?
 In the circle the center point is equidistant to the circumference while it's not for ellipse.




2.      What is the difference between an inscribed and a circumscribed shape?
 Inscribed shape is inside circle while touching circumference of circle while circumscribed shape is outside of circle while touching circle's circumference.




3.      Why is it impossible for a triangle to contain a 180° angle?
 Because a triangle need 3 angles and only can have total of 180 degrees. Hence an angle occupying all the degrees lead to only an angle instead of triangle.




4.      How is a rhombus similar to a square?

 Rhombus and square both has 2 pairs of parallel sides, 4 sides,  and 4 angles.


5.      What is the difference between a right, acute, and obtuse triangle?
Acute triangle has angles under 90 degrees. Right triangle has 90 degress angle. Obtuse triangle has angle above 90 degrees.

Activity 3.1b Linear Measurement with US Customary Units Procedure Conclusion 1.                   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? US customary system has fractions. Moreover SI measurements are only in power of tens while US customary system is not. Engineers need to know this information or else they will end with the wrong measurements, which leads to  too little or too large designs.

Activity 9.1 Product Lifecycle Conclusion 1.       What is meant by product lifecycle ?  Product life-cycle is the process in which the object designed by engineer goes through. 2.       Why is it important for companies who make products to research and determine a product’s potential lifecycle?  This is important to determine the sources of material for product and to change the factory place in accordance with bulk-gaining or bulk-reducing industry. As well as the duration the product will be used by each person and to ensure its proper disposal. 3.       What would you change about your product? Why?  I think the product should be changed to be more tough. Because we didn't do a structural integrity test yet. As well as assembling by more interlocking wood joint. 4.       Do you think your product will evolve or become obsolete over t...
