Wooden planks 300 mm wide by 100 mm thick are used to retain soil with height 3 m. The planks used can be assumed fixed at the base. The active soil exerts pressure that varies linearly from 0 kPa at the top to 14.5 kPa 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. If the wall is propped at the top, determine the lateral force (kN) at the fixed end.
