Part A) As shown below, a beam is subjected to a distributed load and a moment. The length of the beam is = 9.00 , the applied moment is = 50.0 , and the distributed load is = 50.0 . What are the reaction forces and at points A andD, respectively?
Part B) What are the expressions for the shear, , and the bending moment, , within the beam between points A and B in terms of and , the arbitrary distance to the sectional cut from the beam's left end? Express your answers in terms of some or all the variables and separated by a comma.
