Computer application. Construction of an influence line for an indeterminate beam. (a) For the indeterminate beam shown in Figure P12.48, construct the influence lines for M A , R A , and R B by applying a unit load to the beam at 4-ft intervals to compute the corresponding magnitudes of the reactions. (b) Using the influence line in part (a), determine the maximum value of the reaction R B produced by two concentrated 20-kip wheel loads spaced 8 ft apart.
