For the beam shown below, draw the envelop of maximum influence lines for the "absolute" moments. Here the "absolute" indicates the absolute (either positive or negative) value of moment. B 4m 8m (b) (15 points) What is the maximum "absolute" moment that can occur in this beam when a point load of 10KN is applied? Also, specify the location of the point load which produces this maximum "absolute" moment.
