Wooden planks 300mm wide by 100mm thick are used to retain soil height 3m. The planks used can be assumed fixed at the base. The active soil exerts pressure that varies linearly from OkPa at the top to 14.5kPa at the fixed base of the wall. Consider 1-meter length and use modulus of elasticity of wood as 8.5 x 10^3 MPa. Determine the maximum bending (MPa) stress in the cantilevered wood planks.
