2. The beam in Figure 2 is built in at A and loaded by a force P and a concentrated moment Mo at the end B. Find the relation that must hold between Mo and P in order that the slope of the beam should be zero at B. PP BY Mo Figure 2 Use your solution to determine the maximum bending moment for the problem of Figure 3, where a beam of length I, is built in at both ends and loaded by a concentrated force P at the mid-point.
