•1-9. Determine the resultant internal loadings on the cross section through point D. Assume the reactions at the supports A and B are vertical. 6 kN 3 kN/m C D 1.5 m 1.5 m 0.5 m 0.5 m B 1-25. Determine the resultant internal loadings acting on the cross section through point B of the signpost. The post is fixed to the ground and a uniform pressure of 7 lb/ft² acts perpendicular to the face of the sign. 3 ft 2 ft STATE LE 7 lb/ft² A 3 ft B 6 ft 4 ft x Prob. 1-25
