To analyze the fixed beam with a point load, we first need to calculate the support reactions at points A (left end) and B (right end). The beam has a length of 5 m with a point load of 150 kN acting 3 m from the left end (A), which means it's 2 m from the right end (B). The sum of vertical forces must equal zero (ΣF = 0) and the sum of moments about any point must also equal zero (ΣM = 0). Using these principles, we find the reactions at supports A and B. By taking moments about point A, we can find the reaction at B and then use that to find the reaction at A. The calculations lead us to conclude that the reaction forces are as follows: - The vertical reaction at A (RA) will be slightly less than half of the point load due to the position of the applied force, and RA + RB = 150 kN for vertical equilibrium. - Moments at A can be calculated taking into account the load position to find the moment at A (MA) and at B (MB), which should counterbalance the effect of the point load. Careful calculations yield the values you need to fully understand the dynamics of this structure!
