Which statement is correct regarding compression in timber?

The correct statement about compression in timber is that it is found on the inside edge of strained timber. When timber is subjected to bending or load, it experiences different stresses across its cross-section. The inside edge of the bent timber, which is pushed inward, experiences compression as the fibers are compressed together. This is crucial in understanding how timber reacts under load and plays a significant role in construction and safety considerations for timber structures.

Understanding the role of compression helps in evaluating the integrity and performance of timber when it is used as a structural element. The other statements do not accurately reflect where compression occurs in the context of strained timber or misinterpret the dynamics of stress in wood.
