Topic: Section Views

Objective: Creating the proper engineering views to describe an object.  

Material: Life Savers – (Gummy or Hard Candy)torus2

Introduction: A torus is defined by two parameters: the radius of the torus (that is the radius of the
torus’s defining circle, measured from the origin) and the radius of the tube (the perpendicular distance from the defining circle to the surface of the torus). Toroidal Space is the name used to describe the area and volume of a torus or so-called doughnut shape. This special form has been used to describe and/or represent a number of things in our “real” actual material world, as well as, our “imaginary” potential one.

 

STEP 1:

Procedure: Use the provided “Gummy Life Saver” to sketch the CANDY AS YOU SEE IT RIGHT OUT OF THE Package front, top, right side, and isometric views in the space provided.

Questions: Explain the problem with the views? (Hint: hidden lines)

 

 

STEP 2:

Procedure: Use the provided “Gummy Life Saver” and cut it in half directly through the center. Now sketch the CANDY AS YOU SEE it after it has been cut in half front, top, right side, and isometric views in the space provided.lifesaver

QUESTIONS:

  1. Explain why section views are important.
  2. Explain what type of section view this is.
  3. What do the arrows on the cutting plane line represent?
  4. Was there anything different from the left to right side? (size, shape)

 

 

 

STEP 3:

Procedure: Use the provided “Gummy Life Saver” and cut it in a quarter removing a quarter of the candy through the center. Now sketch the CANDY AS YOU SEE it after it has been cut in half front, top, right side, and isometric views in the space provided.lifesaver2

  2. Explain what type of section view this is.
  3. What other items could this type of section view be useful?
  4. Why are the hidden lines removed from the side with the section view?
