Write and sketch all answers on the exam paper in the spaces provided. 2. You may use the provided isometric grid. Note that this grid will not be provided on the final exam an no underlay will be permitted. 3. Sketch only visible edges. 4. Straight edges to aid sketching are prohibited. 5. All other aids, including textbooks, are prohibited. 6. There are multiple versions of this exam. Question A 1. What is the number of degrees of freedom of the following profile? (a) 24 (b) 25 (c) 12 (d) 22 (e) none of a, b, c, or d. Clearly state your answer (a, b, c, d, or e): a. 24 1 ENGINEER 1C03 Week 6 — Midterm (version 2) Fall/Winter 2006–7 Term 1 Name Student Number 2. Which best describes what could go wrong with this profile if dimension V14 is changed? V9=V14 V14=100 V18=V14 /2 V24=V9 /2 V26=90° V28=90° V31=90° Corners are Maintained Between All Intersecting Lines ( i.e. no gaps may exist ) (a) Circle may intersect with the square profile. (b) Circle centre is not ALWAYS located at the intersection of the square diagonal. (c) Perpendicularity is not guaranteed between each two intersecting lines. (d) Equality of ALL edges is NOT guaranteed. (e) Shape segment fault error occurs. Clearly state your answer (a, b, c, d, or e): A 3. Any object can be defined by its boundary. This boundary is made up of surfaces which are called: (a) vertices (b) bridges (c) tangents (d) faces (e) orthogonal Clearly state your answer (a, b, c, d, or e): D 2 ENGINEER 1C03 Week 6 — Midterm (version 2) Fall/Winter 2006–7 Term 1 Name Student Number 4. An isometric pictorial is best described by: (a) a pictorial representation of an object rotated 45 degrees and tilted 36 degrees 16 arcminutes. (b) a type of parallel projection. (c) a type of orthographic projection. (d) normally appearing “three dimensional” (e) all of a, b, c, and d. Clearly state your answer (a, b, c, d, or e): E 5. The term “foreshortening” is best described as: (a) Features are true length or true size when the lines of sight are perpendicular to the feature. (b) A repetative shortening process that reduces a feature to 1/4 its original length. (c) Features are shortened when the lines of sight are not perpendicular to the feature. (d) Parallel features will always appear parallel in all views. (e) No two contiguous areas can lie in the same plane.
