Worked Solution & Example Answer:The hiking stick is telescopic to cater for people of different heights - Leaving Cert Engineering - Question i - 2019
Step 1
Design for Height Adjustability
Answer
The hiking stick can be designed with two or more tubular sections that fit into each other. This allows for varying lengths to accommodate different users.
The outer tube should have a series of drilled holes along its length. A threaded or spring-loaded pin can be inserted into these holes to lock the stick at the desired height. This mechanism ensures that the stick remains stable during use, adapting quickly to the height preference of the user.
Additionally, to enhance usability, the tightening pin can be accessed easily, allowing for quick adjustments while ensuring a secure fit.
Step 2
Diagram
Answer
A diagram should be included illustrating the telescopic design. It could show:
- Outer Tube: Featuring a series of holes for the pin.
- Inner Tube: Fitting into the outer tube.
- Tightening Pin: Indicated in position, showing how it engages with the holes.
Label the parts clearly to reflect the functionality for height adjustment.
