*****************************************************************

 

Classwork 5.1 – Create a cone with a base diameter defined by a design variable base_dia and a height that is twice the base diameter.  Make the initial base diameter equal to 4 inches, then experiment with changing it.  Plot the front-right isometric view of this object with base diameter equal to 2 inches.  Include a completed titleblock on the drawing, and submit a hardcopy.

 

Classwork 5.2 – Create a solid model of the part shown in Figure 4.85F #69 on p. 146 of TGC (Figure 6.97 #69 on p. 369 of FGC).  Plot the front-right isometric view of this object and include a completed titleblock.  Submit a hardcopy.

 

Classwork 5.3 – Create a solid model of the object shown in Handout CW5.3.  Plot the front-right isometric view of this object and include a completed titleblock.  Submit a hardcopy.

 

Homework 5.1 – Create a solid model of the object shown in Handout HW5.1.  Plot the front-right isometric view of this object (include a completed titleblock) and submit electronically.

 

Homework 5.2 – Using the revolve command, create a solid model of the part shown in Figure 4.85G #74 on p. 147 of TGC (Not in FGC – attached as a handout).  Plot the front-right isometric view of this object (include a completed titleblock) and submit electronically.

 

Homework 5.3 – Make an isometric sketch of the object shown in Figure 9.75 #13 on p. 510 of FGC (Figure 7.60 #13 on p. 431 of FGC).  Use a scale of 3 iso-blocks = 1 square block in the text.

 

Homework 5.4 - Read Chapter 11, pages 537 - 553 in TGC (sections 6.11 – 6.14, pages 351 - 357 in FGC) AND Chapter 14, pages 641 - 668 TGC (Chapter 8, pages 439 - 466 in FGC).
