Question:

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 \(8 \mathrm{ft}\) apart.
