TIMBER TOPICS

The video discusses innovative methods for measuring and utilizing timber. A machine developed by the Forest Products Research Laboratory can measure timber volume with high accuracy. The laboratory also studies insect pests to prevent timber damage. A new laminating process allows for the creation of long timber beams from smaller pieces. Additionally, the strength of timber components is tested to ensure reliability in construction.

What is the accuracy level of the machine developed by the Forest Products Research Laboratory for measuring timber volume?

• Plus or minus 0.5%

• Plus or minus 1%

• Plus or minus 5%

• Plus or minus 10%

How does the study of insect pests benefit timber usage?

• By preventing destruction before it occurs

• By increasing timber growth rate

• By improving timber color

• By reducing the cost of timber

What is the pressure applied during the laminating process to bond timber pieces?

• 200 pounds per square inch

• 100 pounds per square inch

• 150 pounds per square inch

• 50 pounds per square inch

What is the maximum length of beams and joists that can be created using the new laminating process?

• 250 feet

• 100 feet

• 150 feet

• 200 feet

What is being tested in the final section of the video?

• The color of timber

• The cost of timber

• The weight of timber
