Engr 114engineering Graphics Everett Community College Week 8 Assignments Homework Deliverables (due at the beginning of class Monday (06/05)) Instructions: Create a SolidWorks part model of the wrench shown below. The dimensions are in millimeters. Use equations to and dimension choices to incorporate the following design intent. Note some of these might differ from the dimensions given on the figure. · Large end hex size equal to small end hex size + 5 · Outer diameter of each end (at midplane) is equal to the hex size + 15 · Distance from center of hex to end of straight handle equal to twice the hex size · Length of straight handle section = (larger hex size – 10) x 10 Create an engineering drawing with a design table. Show the variable dimensions as labels analogous to figure 5.149 (on page 183) in your text. Use auxiliary views (not sections) for wrench ends and a section view for the wrench handle. Include the dimensions for 20 mm, 30 mm, and 40 mm (large end) wrench configurations in the design table on your drawing. Turn in the following to document your work: · A printout of your part drawing on B-size (11 x 17) paper. · Submit your drawing per instructor’s instruction.

Paper For Above instruction

The task involves creating a parametric SolidWorks model of a wrench with specific variable dimensions and then illustrating it with detailed drawings including a design table. The purpose of this assignment is to develop proficiency in parametric modeling, dimensioning strategies, and drawing techniques within SolidWorks, which are crucial skills in mechanical design and engineering graphics courses.

The initial step is to model the wrench in SolidWorks by carefully defining all key dimensions and features in relation to variable parameters. Based on the instructions, the variable parameters include the hex sizes at the large and small ends, the outer diameter of each end, the distance from the center of the hex to the end of the straight handle, and the length of the straight handle section. Each parameter must be linked via equations to ensure consistency and to facilitate easy updates for different wrench configurations.

Specifically, the large end hex size is set to be equal to the small end hex size plus 5 mm, establishing a direct relationship that maintains proportionality in the design. The outer diameter of the wrench ends at midplane is to be equal to the respective hex size plus 15 mm, ensuring a visual balance and appropriate clearance for wrench fits. The distance from the tire's center of the hex to the end of the straight handle is defined as twice the hex size, creating a proportional length that adjusts with changes in hex dimensions. The length of the straight handle itself is calculated as (larger hex size – 10) multiplied by 10 mm, linking the handle length directly to the size of the wrench's end features.

Once the parametric model is established, the next phase involves creating an engineering drawing that presents the part clearly with a design table. The design table enables multiple configurations—specifically for wrench sizes with large end diameters of 20 mm, 30 mm, and 40 mm—by specifying the variable dimensions for each case. This table provides a visual and tabular method for understanding how changes in parameters affect the overall geometry.

The drawing should include labeled dimensions for each variable feature, using style conventions similar to those in Figure 5.149 of the course textbook. To provide comprehensive views, auxiliary views should be used to display the wrench ends, avoiding section views, while a sectional view is appropriate for the handle, capturing the internal features and dimensions accurately. These views help in understanding complex geometries and dimensioning details without cluttering the overall drawing.

Finally, the finished drawing must be printed on B-size (11 x 17 inches) paper and submitted according to instructor instructions. Proper documentation ensures clarity in communication of the design intent, correct interpretation of the variable parameters, and demonstrates understanding of both modeling and drawing standards. This assignment not only enhances technical skills but also prepares students for real-world engineering documentation tasks.
