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 t...
