The figure below shows a horizontal beam AB (negligible weight) that is subjected to four forces. The 100N and 20N forces are acting vertically down. The 60N and 40N forces are at an angle of 30with respect to the vertical and horizontal respectively. Find (a) the magnitude of resultant force (b) the distance of the resultant from the support A (c) The reaction forces developed at the supports A and B.
