PRACTICE PROMPT
Use this fictional setting to practise clear reasoning. It is not an assessment or institution paper.
The setting
A steel beam penetrated by a 400 mm diameter service duct near mid-span.
Your task
Draw the opening and its stiffening.
What a useful response would show
Position relative to the shear and moment envelope, and stiffening that suits it.
Reflect afterwards
- What assumption mattered most?
- What would you check before using this on a real project?
- Could another engineer follow your recommendation?
