Worked Solution & Example Answer:Details of a Bench Mounted Nutcracker are shown in Fig - Leaving Cert DCG - Question C-5 - 2015
Step 1
Sectional elevation on A-A
Answer
- Begin by sketching the outline of the base part, ensuring it is accurately represented with the dimensions provided.
- Next, draw the vertical slide rods, ensuring they are positioned correctly in relation to the base.
- Add the spindle mount by tracing its rectangular outline and associating it with the moving jaw.
- Sketch the moving jaw and its details, then represent the cam handle accurately in its vertical position.
- Ensure to include all essential details such as circles, tangents, and any required fillets to give a complete representation of the assembly.
- Use hatching to distinguish different materials and provide a professional finish to the drawing.
Step 2
Shortest vertical distance between base and moving jaw
Answer
- Establish the center of the large circle when in the rotated position (45°). This involves determining the geometric center based on the dimensions provided.
- Measure the vertical distance using the 40mm and 20mm distances to ascertain the required spacing between the components during operation.
- Finalize the drawing by illustrating this distance clearly, with appropriate labeling to indicate its significance in the mechanism's operation.
