How does eucalyptus’s resistance to bending stress compare to teak?

When comparing eucalyptus and teak in terms of bending stress resistance, several factors come into play. Teak (Tectona grandis) is renowned for its exceptional strength and durability, with a high modulus of rupture (MOR) of around 14,000 psi, making it highly resistant to bending stress. Its natural oils and dense grain structure contribute to its robustness, often making it a preferred choice for high-stress applications like shipbuilding and outdoor furniture.

Eucalyptus, on the other hand, varies widely among species but generally offers moderate bending resistance. For instance, Eucalyptus grandis has an MOR of approximately 10,000 psi, which is lower than teak but still suitable for many structural uses. While eucalyptus lacks the natural oils that enhance teak's resilience, it is often more affordable and sustainably sourced, making it a practical alternative for certain projects.

In summary, teak outperforms eucalyptus in bending stress resistance due to its superior density and oil content. However, eucalyptus provides a cost-effective and eco-friendly option for less demanding applications. The choice ultimately depends on budget, sustainability priorities, and specific project requirements.
