## Report assignment of SRT153 – Building Materials Science

Report assignment of SRT153 – Building Materials Science
1. Watch the videos documenting timber testing and summarise your observations
(approximately 350 words). The following needs to be noticed/ commented (1) testing
equipment, (2) geometry of the samples, (3) visual appearance/ grading of each sample, (4)
method of force application (5) failure modes and (6) safety aspects related to testing.
2. Copy Table 1 to your assignment/ report.
3. Examine the seven photographs and state moisture content (MC) in Table 1.
4. Calculate compressive strength [in MPa] of each sample and fill in the results in Table 1.
The following equation/ formula (i) is to be used to calculate compressive strength:
i. FORMULA; Strength (Pa) = Force (N) / Area (m2)
5. Propose a simple method of determining density of any of the samples presented in Table 1.
6. Propose a simple method of determining moisture content od timber sample in case you
have no access to ‘wood moisture meter’.
( Please have a look to the attachments )
Comments from Support Team: this link you can use to see the videos.
