← Logic & PuzzlesA bridge truss is modeled as a linear system of forces; if one support fails, which outcome is most likely?
A)Forces redistribute without consequence
B)Material stress decreases uniformly
C)Stress concentrates and exceeds limits✓
D)Equilibrium maintains structural integrity
💡 Explanation
When a support fails, the linear system modeling the truss redistributes forces via Static Determinacy, concentrating stress on the remaining supports. Therefore, stress concentration and exceeding material limits becomes likely, rather than uniform stress reduction or maintained equilibrium, because force distribution changes drastically.
