    Module 21 Competency Test No. 4 Open Book

    Learning Outcomes

    When you have completed this module, you will be able to:

    1. Within a two hour time limit, complete a written exam and a lab exercise.

    The Inventor book was written with competency based modules. What that means is that you have not completed each module until you have mastered it. The Competency Test module contains multiple choice questions and a comprehensive lab exercise to test your mastery of the set of modules that you completed. There are no answers or keys supplied in a Competency Test module since it is meant to be checked by your instructor. If there are any parts of this module that you have trouble completing, you should go back and reread the module or modules containing the information that you are having trouble with. If necessary, redo as many lab exercises required until you fully understand the material.

    If you are Completing this book:

    • Without the aid of an instructor, complete the written test and the lab exercise.
    • In a classroom with an instructor, the instructor will give instructions on what to do after you have completed this module.

    Step 1

    Project the Center Point onto the Base plane.

    Step 2

    Note the location of X0Y0Z0. Draw the necessary sketches and extrude them to produce the solid model shown below. Apply all of the necessary geometrical and dimensional constraints to maintain the objects shape and size. All sketches must be fully constrained. (Figure Step 2A and 2B)
