Handwritten solution please ### Problem DescriptionFor **Problems 9.1 through 9.6**, use the virtual work method to determine the deflection of each of the joints indicated. **E = 29,000 ksi** for all members unless otherwise indicated. The cross-section of each member is given as **in²** unless noted otherwise.#### P9.1- **Objective:** Find \(\Delta_{BX}\) and \(\Delta_{EY}\).- **Bar areas**: - AB = 7 - BC = DE = EC = 2 - AD = BE = 4 - DB = 6- **Forces and Distances:** - A 20 k force is applied at joint B. - A 40 k force is applied at joint C (15 ft above point). - A 10 k force is applied at joint E. - The distances from D to B and D to E are each 20 ft.- **Answers:** - \(\Delta_{EY} = 0.753 \, \text{in.}\) - \(\Delta_{BX} = 0.173 \, \text{in.} \rightarrow\)### Diagram ExplanationThe diagram is a truss structure with five joints labeled A, B, C, D, and E. - **Structure Layout:** - Points A, B, and C are aligned horizontally with equal spacing (20 ft apart). - Points D and E are directly below points A and B, respectively, each connected by diagonal members. - DB and DE are vertical members each 15 ft long.- **Member Connections:** - AB and BE form the top and middle horizontal connections. - AD, DB, and ED form the vertical and diagonal connections. - BC, DE, and EC form the further connections from B and C.This description serves to explain the layout and problem requirements for calculating joint deflections using the given parameters.
