PRACTICE PROMPT
Use this fictional setting to practise clear reasoning. It is not an assessment or institution paper.
The setting
A cantilever retaining wall retaining 3.5 m of granular fill with a 10 kN/m² surcharge.
Your task
Check overturning, sliding and bearing, then size the stem.
What a useful response would show
The three stability checks done before any reinforcement is considered.
Reflect afterwards
- What assumption mattered most?
- What would you check before using this on a real project?
- Could another engineer follow your recommendation?
