Problem 4.5-25 The simple beam AB shown in the figure supports a concentrated load and a segment of uniform load. (a) Draw the shear-force and bending-moment diagrams for this beam. (b) Find the value of P that will result in zero shear at x = 4.2 m. Draw shear-force and bending-moment diagrams for this case. A P-22.0 kN ! x=4.2 m !30 kN/m B -3.0 m- +1.5 m 6.0 m 000
