PRACTICE PROMPT
Use this fictional setting to practise clear reasoning. It is not an assessment or institution paper.
The setting
A tank wall 6 m high retaining water, 400 mm thick reinforced concrete.
Your task
Size the reinforcement including crack width control.
What a useful response would show
Serviceability governing, with early-age thermal cracking considered.
Reflect afterwards
- What assumption mattered most?
- What would you check before using this on a real project?
- Could another engineer follow your recommendation?
