1. Given: A structure shown below Find: (1) Determine the magnitudes and locations of the two distributed loadings. In other words, determine the magnitude and location of the loading between A and C, and those of the loading between D and B. (2) For the member DEB, (a) take the moment at B and find the reaction at E and (b) then find By by either Fy= 0, or EMp = 0. (Recall that support conditions at B and E are rollers, so there are no reactions in x-direction.) (3) For the whole structure, 3 unknown forces and moment at A (Ax, Ay and Ma) are the only unknowns. Determine those 3 unknowns at A. 900 N/m 900 N/m B A C D 2E - 3 m 3 m - 4 m - 3 m3 m-
