Worked Solution & Example Answer:Details of a Juice Press, which was bought in pre-assembled format, are shown in Fig - Leaving Cert DCG - Question C-5 - 2009
Step 1
Draw a full size sectional elevation on A-A showing the parts fully assembled
Answer
To create the full-size sectional elevation drawing on A-A, start by sketching the elevation of the Juice Press with all components, including the Juice Strainer, Hinges, Press Lever, Juice Cup, Hinge Cap, Vertical Bar, and Plunger. Ensure that the Press Lever is depicted in a horizontal orientation. Represent the sectional cut through A-A accurately, ensuring to label all components according to the parts list provided. Utilize appropriate dimensions and scaling as shown in Fig. C-5.
Step 2
Determine the distance between the centre of circle O and the horizontal plane when the Press Lever is in this position
Answer
To find the distance from the centre of circle O to the horizontal plane when the Press Lever is in the lowered position, first note the radius of circle O. Using the geometry of the situation, measure how far the lever has fallen until C touches S. The final distance can be calculated based on the height of C above the horizontal plane when it meets the surface of S. Using appropriate trigonometric principles, calculate the vertical drop in elevation, and subtract this from the initial height of the centre of circle O to get the required distance.
