Question $2$

Consider the problem of analyzing the beam shown

below using the Force Method. Using the roller

support at $B$ as a redundant support compute the

support reaction at $B(R_B)$ and then at $A(R_A)$ for the

beam data shown in Table $1.$ Assume that the beam

has a fixed support at A and a roller support at $B$ and

that El is the same for all members. Enter in the

answer box shown below the value of $R_A($support

reaction at A$)$ and the deflection ${}_{BO}$ expressed as

an EI ${}_{BO}$ value, separated by a comma $($e$.$g$.$ For $R_A=$

$20\mathrm{.}7$ kN and $EI{}_{BO}=150\mathrm{.}4,$ enter your answer as:

$"20\mathrm{.}7,150\mathrm{.}4").$
