Consider a structure loaded as shown below. Note that force F points in the x- direction, W in the-y-direction and P in the -z-direction. 2m D C 1.2 m Z P y W B X Cross-section at C B a N X Suppose posts CD and DE are both solid circular sections with radius r = 8 cm. Also take P = 10 kN, W = 5 kN and F = 4 kN. a) Clearly identify the sources of stress at the points labeled and in the cross- section at C above. b) Calculate the stress state at these points.
