The post has a rectangular cross-sectional area. It is fixed-supported at its base and the loadings are applied as shown. The 500N force acts on the centroid of the cross-sectional area, the 400N force acts at the corner and the 300N force acts on the side of the block, along the axis going through the centroid. A and B are in the same cross-section. B marks the corner point, A is located on the edge, a distance of 5 cm from point B. a. Draw a section cut and find the internal loadings at a cross- section containing point A. You MUST use the coordinate directions we used in our class example (x-axis down, y-axis out of page, and z-axis to the left). 300N 30cm 30cm 20cm 80cm 400N 20 cm 20 cm B 500N
