Theoretically substantiate the reaction forces arrived at by the software BeamBoy and prove that they are correct by applying the first principles given that the beam is 8m long in total length with a distance of 4m which is under a distributed load of 7.5Kn and a point load at the end of the beam 15Kn. show the reaction forces at all point A and B( 0-4M) and show the bending stress, moment and deflection

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
