To find the end support reactions for the fixed beam, we can use the equilibrium equations. The total load acting on the beam is 150 kN, and it creates moments around the fixed supports. We can sum moments about one end (let's say the left end): 1. The moment due to the point load about the left end is \(M = F \times d\), where \(F = 150 \, \text{kN}\) and \(d = 3 \, \text{m}\). 2. Calculate the counteracting moment produced by the reaction at the right support. Eventually, by solving the equations of equilibrium (sum of vertical forces = 0 and sum of moments = 0), we can find the reactions at supports (RA, RB) and the fixed moments (MA, MB). For the fixed support moments: 1. The moment at the left end can be determined by taking the clockwise moments about that point and setting them equal to the counterclockwise moments due to the applied loads. 2. You end up with equations involving the reactions we calculated previously. This process will lead you to finding both the support reactions and the support moments at each end of the beam effectively. Happy calculating!
