Details of a Handheld Nut Cracker, as shown on the right, are given in Fig - Leaving Cert DCG - Question C-5 - 2022

For the sectional elevation A-A, initiate by drawing the outline of the Nut Cracker as represented in the side view. This section will be taken through the most central part of the device, ideally through the area where the jaws meet the handle.

Using the visible dimensions (such as the width and radius), construct the outlines of the handles and jaws in their respective positions. Be precise with angles and circular curves, which are critical in accurately representing the crank’s functionality. Ensure to depict the sections of the pin holes clearly to illustrate how they fit into the jaws.

The outline of the bottom handle should be drawn first, showcasing its ergonomic shape that blends into the starting base of the Nut Cracker. Ensure all relevant dimensions from the parts list are included, specifically accounting for any curvature as noted in the figure.

After outlining the bottom handle, detail the circular hole intended for the pin. This hole must conform to the dimensions given, ensuring that the representation is accurate for functionality.

Next, create the outline of the top handle, integrating a similar approach as used for the bottom handle. Ensure that the contours reflect the design and provide space for the user’s grip.

Include the circular hole for the pin in the top handle as per the dimensions provided. This is crucial for showcasing how the top handle can move relative to the bottom handle.

Proceed to draw the outline of the bottom jaw. This part should fit snugly against the bottom handle, creating a cohesive unit that effectively cracks nuts.

Following the bottom jaw, depict the top jaw. The interaction between the top and bottom jaws is essential, as they must align when the nut is secured. Ensure proportionate sizing based on the provided dimensions.

Draw the pin holders on both the top and bottom handles. Indicate the circular holes that will accommodate the pins, crucial for the assembly of the components.

Lastly, illustrate the positions of the 50mm and 42mm pins. Make sure they are accurately represented in terms of location and proportion to the handles and jaws.

Utilize hatching techniques to indicate the different materials or sections within the elevation view. Centre lines should be added to clarify the symmetry and rotation of moving parts.

Ensure your drawing is neat, legible, and all components are visibly labeled. A clean presentation not only enhances readability but also allows for a clearer understanding of the 3D aspects of the Nut Cracker.
