A wooden block of length 400 mm, width 50 mm and depth 100 mm is subjected to uniaxial load as shown in the figure. An inclined plane ABCD is shown which makes an angle θ with the XZ plane and the line CD is parallel to the Z-axis. The normal stress on the plane ABCD is 1 n σ when o θ 30 = and the normal stress on the plane ABCD is 2 n σ when o 120 θ= . The value of 2 1 n n σ σ is __________ 10 kN X 10 kN θ A C D B Y Z 400 mm
