Are you buying the Wrong lumber? 🤔 #carpentry #framing #test
What happens here
Following the first test, the 2x4 lumber piece labeled 'Plain' (without the pith) is placed into the hydraulic press, maintaining the same orientation as the previous sample. The hydraulic pump is operated again, progressively increasing the pressure on the board. The pressure gauge indicates a significantly higher load before failure. This board resists stress up to approximately 16,000 pounds of pressure before it breaks. The nature of its failure appears more abrupt and complete, consistent with higher energy storage and greater inherent strength.
Goal: Measure the breaking strength of lumber without pith.
