Worked Solution & Example Answer:Details of a Clamp for securing a Camera to a circular bar are shown in Fig - Leaving Cert DCG - Question C-5 - 2010
Step 1
Draw a full size sectional elevation on A-A showing the parts fully assembled.
Answer
To create a full-size sectional elevation of the clamp on line A-A:
-
Start with the Fixed Jaw: Draw the fixed jaw with a diameter of 24mm. Ensure it is aligned correctly with the camera securing mechanism.
-
Draw the Swivel Mount: The swivel mount should be placed to allow rotation. Ensure its diameter matches that indicated in the figure.
-
Incorporate the Adjustable Jaw: The adjustable jaw must also have a diameter of 24mm and should be represented in the correct position in relation to the fixed jaw.
-
Include the Clamp Screw and Locknut: Depict the clamp screw and locknut, ensuring they connect the adjustable jaw to the fixed jaw properly.
-
Represent the full assembly accurately: Ensure that all parts fit together logically and reflect the 3D illustration provided.
Additional Details:
- Use dashed lines where necessary to indicate hidden parts.
- Incorporate any cut details for better clarity.
- Dimensions must be readable and clearly labeled.
Step 2
Determine and indicate on your drawing the maximum rotation of the swivel mount from the extreme left to the extreme right position.
Answer
To denote the maximum rotation of the swivel mount:
-
Calculate the Rotation Angles: The angle of rotation can be determined by assessing the limits of the swivel mount.
-
Indicate the Extreme Positions: The extreme left position should be marked, and the rotation to the extreme right position should be calculated. The marking scheme demonstrates that the angle of rotation is to each side of the center, giving a total of:
-
Draw Arrows for Clarity: On your diagram, draw arrows or arc symbols to clearly indicate the rotational movement from one extreme to the other. Label these arcs with the calculated degree of rotation for clarity.
