absolute value of the shear and bending moment in the beam by the semi-graphical method. Explain how you come up with the solution/Answer. CO 23 kN 30 kN/m B A 3 m- 2 m 1 m

Refer to Figure P6.4. A strip load of q = 900 lb/ft2 is applied over a width B = 36 ft. Determine the increase in vertical stress at point A located z = 15 ft below the surface. Given: x = 27 ft. Figure P6.4

For the beam shown: (a) determine the distance a for which the maximum positive and negative bending moments in the beam are equal; and (b) draw the corresponding shear and bending moment diagrams for the beam.
