Situation - A temporary retaining wall is supported by timber
post as shown. The post can be considered fixed at the bottom.
The soil exerts a pressure on the wall that varies uniformly
from 0 kPa at the top to 15 kPa at the bottom.
Given:
Dimension, b x d = 100 mm x 200 mm
Spacing of post = 800 mm
Height, H = 2.4 m
