Day 15  Intro to Engineering Allen Sam 7-3-18 Activities 7.3 and 7.4 7.3 Tolerances 1.       Study the drawings below to identify specified tolerances. a.       Highlight each dimension that has a tolerance associated with it using something like a highlight marker. b.       Identify the type of tolerance in each highlighted example by labeling each tolerance dimension with one of the following: limit dimensions, unilateral tolerance, or bilateral tolerance. c.       Label each identified tolerance with a separate letter, A through Z. d.       Beginning on a new page in your engineering notebook for each part, record the letter of each tolerance identified on that part drawing, the type of tolerance, a short written phase that describes the dimensional variation allowed for that dimension, the tolerance (a number representing the total allowed dimensional variation), and an explanation as to why that particular dimension requires a tolerance.

Day 12  Intro to Engineering Allen Sam 6-27-18 Activities 5.5a and 5.5b 5.5a   Conclusion:  1.        What 3D CAD functions could be used to create a wire coat hanger? I would use the sweep, loft, and revolve functions of CAD to create the coat hanger from the front view and a side view. Activity 5.5b \ Conclusion:  1.    What CAD feature would be used to most efficiently model a baseball bat (Extrude, Loft, Revolve, Sweep)? Explain your answer. I would use the revolve tool to create the baseball bat because the baseball bat is cylindrical     2.    How does a 3D CAD solid model program display the progression of work involved in creating a model? You can see progression of the work of a project by showing the constraints and CAD features that were used. 3.    If a mistake is made, how does the user make a correction without using the undo function? The user would either use the delet
