1.8. Impact Test

Try these first

1. 1.

   What is the purpose of the Impact Test?

   Hint

   Think about timber's performance under sudden loading.

2. 2.

   Name one apparatus used in the Impact Test.

   Hint

   Recall the names discussed in class.

3. 3.

   What does the Impact Test measure in timber?

   • Strength under compression
   • Resistance to sudden shock
   • Moisture content

   Hint

   Consider what the test is fundamentally evaluating.

4. 4.

   True or False: A higher energy absorbed indicates better toughness in timber.

   • True
   • False

   Hint

   Recall the relationship between energy absorption and timber strength.

5. 5.

   A timber beam is tested using a Charpy impact test and absorbs 25 Joules of energy before breaking. What can you conclude about its suitability for a structural application?

   Hint

   Compare this value with known benchmarks for timber strength.

6. 6.

   In a scenario, two different timber types are subjected to impact testing. Timber A absorbs 15 Joules, while Timber B absorbs 40 Joules. Discuss the implications of these results regarding structural integrity.

   Hint

   Think about the implications of choosing between these values in construction.
