simply supported beams??? 1. Can anybody help me? please. This seems like I have gone completely off track. A simply supported beam of length 6m supports a vertical point load of 45kN a distance of 4m from one end. If the maximum allowable bending stress is 120MPa: (there were 4 previous questions on point loads, which I have completed) recalculate the reaction forces at either end, taking into account the actual weight of the beam as a UDL. Determine the actual maximum bending stress. I'm not sure if the UDL would be a point load equal to 180kN acting 2m from one end, I have worked Rb=60kN and Ra=165kN. I have the final answers and they should be Ra=16.15kN and Rb=31.15kN. I really can't see how to get to this? Thanks to anyone that can help!
