in question 4_27 at B what is this suppose to be ? is it a pin like in part A of the beam ?

Draw the shear and moment diagrams for the beam. 4-26. 50 kN · 12 kN/m 40 kN -2 m 4 m Prob. 4-26 4-27. Draw the shear and moment diagrams for the beam. 6 kN/m 1 kN·m 5 Prob·4-27 *4-28. Draw the shear and moment diagrams for the beam (a) in terms of the parameters shown; (b) set Mo-500 N·m, L = 8m. Mo Mo L/3 L/3 L/3 Prob. 4-28 4-29. Draw the shear and moment diagrams for the beam 1.5 kN mm

Solution

This is case of simply supported beam. This is same as above question. U can solve this question by as simply supported beam with udl over whole span and also don\'t forget to consider the moment at point A.
