We were unable to transcribe this imageProblem 1 The truss (all joints are pinned) structure in figure 1 is made of members with cross sectional area A = 1 in, with a linear elastic, homogeneous, isotropic material with an elastic modulus. E-10E6 psi and a coefficient of thermal expansion, α-6E-6 °F-ι. The structure starts out at a uniform temperature of 65°F and is raised to a final temperature of 120°F while being subjected to a concentrated load Po- 5,000 lbs...

Problem 2: The figure below shows a two-member plane truss supported by a linearly elastic spring. The truss members are of a solid circular cross section having diameter, d = 20mm, and E = 80 GPa. The linear spring has a stiffness constant of 50 N/mm. A load of 15 kN is applied at 3 at an angle of 50 degrees with the horizontal. Find (a) The global displacements of the unconstrained node and (b) compute the reaction forces and...
