2. For the hinged beam system shown in Figure 1: a) Determine reactions at $\mathrm{A}$ and $\mathrm{E}$. Also determine reaction at pin $\mathrm{C}$. b) draw segment FBDs, establish the equations of the internal shearforces and bending moments of segments $AB,BD$, and $DC$, i.e. determine $V_{\mathrm{AB}}(x),M_{\mathrm{AB}}(x),V_{\mathrm{BC}}(x),M_{\mathrm{BC}}(x),V_{\mathrm{CE}}(x),\&M_{\mathrm{CE}}(x)$. c) draw the shear-force and bending moment diagrams (Note: Provide the shear and bending moment values at $A,B,C,E$ and other critical locations), identify the most critical section, and record the values of $\mathrm{V}$ and $\mathrm{M}$ in the most critical section (write the values \& units in the box located at the bottom of template), d) at the critical section identified in part (b) above, determine the maximum tensile and compressive stresses $\left({\left({?}_{\max }\right)}_t\&{\left({?}_{\max }\right)}_c\right)$, the maximum transverse shear stress ${\left({?}_{\max }\right)}_V$, and, e) the absolute maximum shear stress, ${?}_{\max }$. (Note: Explore all points of interest of the identified critical section to determine the largest absolute maximum shear stress.) Note: Use the following cross-sectional properties for stress analysis: Figure 2. Cross-Section of Beam - $\stackrel{?}{y}=9.25\mathrm{in},I_{NA}=I_z=398.5{\mathrm{in}}^4$.
