Problem $4.(20)$

Sketch the deformed shape and a$)$ determine the approximate support reactions, b$)$ sketch the moment diagram for beam GHI for the frame below. Use Portal method of analysis. $($Show location of hinges; Sketch each free body diagram and show each force being calculated; box your answers with appropriate units and direction$).$

You Must:

Sketch deformed shape and show inflection points.

Show each FBD and write equilibrium equations for each unknown and demonstrate solution completely

Be careful in sketching internal force orientations from FBD to FBD

For the given truss, apply virtual work method and determine required values, Members have area of $4\mathrm{.}5i{n}^2,$ and $E=29,000$ksi.

a$)$ What is the vertical displacement at G due to applied loads.

b$)$ If temperature on AE and EG is raised by $65F,$ what is the total vertical displacement of G $($including the given applied loads, $=6{10}^{-6}\frac{1}{F}).$

c$)$ What is the horizontal displacement of point G under the combined applied $15$ k vertical loads $($as shown$)$ and a temperature increase on members AE and EG by
