Chapter 10, Problem 10.25QP
A pine wood specimen was prepared with actual dimensions of 50 mm × 50 mm × 250 mm and grain parallel to its length. The deformation was measured over a gauge length of 200 mm. The specimen was subjected to compression parallel to the grain to failure. The load–deformation results are as shown in Table P10.25.
