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.

Question
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.
