The influence line is for $V_{{40}^{-}}=$shear just left of ${40}^{\text{'}}.$ A load of $0\mathrm{.}5ki\frac{p}{f}t$ is placed from $0^{\text{'}}$ to $30\text{'}.$ A load of $0\mathrm{.}2$kip$\frac{s}{f}t$ is placed from ${30}^{\text{'}}$ to ${40}^{\text{'}}.$ Determine $V_{{40}^{-}}$in kips to two decimal

places. Use the correct sign.
