Engineering Adds Constraints
An engineer must build something that works in the real world.
Learning objectives
- Define and explain engineering adds constraints.
- Apply engineering adds constraints to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Definition
An engineer must build something that works in the real world. Cost, safety, time, and materials all matter. A crane must lift scrap and also drop it. A clinic thermometer must not shatter and must be readable. That is more than knowing the formula.

WHAT — ENGINEERING ADDS CONSTRAINTS
An engineer must build something that works in the real world. Cost, safety, time, and materials all matter. A crane must lift scrap and also drop it. A clinic thermometer must not shatter and must be readable. That is more than knowing the formula.
HOW — Use the idea
Identify what is given, select this topic's rule or evidence, apply it one step at a time, and check the result.
In simple words
Do not merge engineering adds constraints with a neighbouring idea that uses a different definition, rule, or method.
