Problem 2: The grains of wood in the bar make an angle of 20° with the horizontal as shown. Determine the normal and shear stress that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N. Solve this problem using 1- Stress transformation equations 2- Resloving the 250 axial force into an normal and shear forces on the inclined plane and then dividing these force on the area (inclined area) to get the normal and shear stresses -300 mm- 160 mm 250 N- 25 mm- 20° 250 N
