Q3. Consider the production and consumption of widgets. Suppose the consumption of widgets causes a negative externality. a. Illustrate the externality problem in the widget market using a supply-and-demand diagram. That is, draw and label the private marginal value (MV) curve, the social marginal value (SMV) curve, the private marginal cost (MC) curve, the social marginal cost (SMC) curve, the market equilibrium level of output ($Q_{LF}$), and the efficient level of output ($Q_{EF}$). b. Using the same diagram, explain why the existence of the externalities causes market failure. c. Use your diagram to show and explain how to use a \"corrective tax/subsidy\" to solve the externality problem.

3. Consider the assembly of three uniaxial bar elements or members, as shown. If motion is restricted to the horizontal direction, apply the direct method of the finite element method to determine the displacement of the rigid member, element forces, and reaction forces from the wall. Include a finite element model showing your local and global labeling and a free body-diagram of your structure. Show all of your work (including your element stiffness matrix and applied boundary conditions) for full credit. $K_1 = 60 \text{ N/cm}$ $K_2 = 35 \text{ N/cm}$ $K_3 = 70 \text{ N/cm}$ $F_1 = 50 \text{ N}$
