The A-frame shown in Figure 2 is loaded with horizontal and vertical loads $P_X$ and $P_Y$. Bar 'A' is acrylic and bar ' $\mathrm{B}$ ' is 1050 aluminum. a) Determine the nodal displacements at the supports. $(0,0,3.303,0.585,0,0)\mathbf{mm}$ b) Determine the reaction forces at the supports. $(?8.632,?14.95,?66.37,115.0)\mathrm{kN}$ c) Determine the normal stresses in each bar. (17.27, 316.0) MPa d) Do the calculated displacements in a) make sense? Discuss briefly.
