C.16.RM:3 - Forces
| Force | Tension |
|---|
| Better model and simpler conditions | Describing an influence can be costly; controlling it can change the subject or require new equipment. |
| Fault diagnosis and sufficient repair | Several causes may remain possible while an available change already restores the needed result. |
| Repeated data and structural ambiguity | More readings help only through the distinctions or error reduction their relation supports. |
| Changed arrangement and original target | A more convenient experiment may answer a different question. |
| Numerical correctness and measurement adequacy | Correct calculation can implement an inadequate model; a suitable model can be computed incorrectly. |
| Full restoration and useful completion | A conditional result or adequate bound may settle the work before every uncertainty is removed. |
