A simple beam AB supports two connected wheel loads P and 2P that are distance d apart (see figure). The wheels may be placed at any distance x from the left-hand support of the beam.
(a) Determine the distance x that will produce the maximum shear force in the beam, and also determine the maximum shear force V max.
(b) Determine the distance x that will produce the maximum bending moment in the beam, and also draw the corresponding bendingmoment diagram. (Assume P = 10 kN, d = 2.4 m, and L = 12 m.)
