Problem 5.82 The bent rod is supported at A, B, and C by smooth journal bearings as shown in (Figure 1). Figure Part A 1 ft A 4 ft F1 45° C 5 ft B 2ft 3 ft 30° y 45° F2 Determine the magnitude of F2 which will cause the reaction Cy at the bearing C to be equal to zero. The bearings are in proper alignment and exert only force reactions on the rod. Set F₁ = 250 lb. Express your answer using three significant figures and include the appropriate units. F2 = Value lb Submit Previous Answers Request Answer

Bill Katz prefers more of good 1 to less and he prefers less of good 2 to more. Bill has convex preferences. If we draw his indifference curves with good 1 on the horizontal axis and good 2 on the vertical axis, then his indifference curves have positive slope but get steeper as the amounts of good 1 and good 2 rise.

You are a Program Manager for the Department of Public Health in the City of Atlanta, and you invested $5 million over the last three years on a new initiative to reduce teenage pregnancy in the city. Data on the effectiveness of the program are inconclusive. You are weighing the costs and benefits of continuing the program for another three years. In making your decision, which facts are relevant? Select all that apply. Group of answer choices How much money you have already invested in the program over the last three years The financial cost of the program over the next three years The number of Atlanta-based teenagers who will be able to participate in this program over the next three years The benefits accrued from pursuing a program that is the next best alternative to the current program under consideration

A wire carries a steady current of 2.00 A. A straight section of the wire is 0.750 m long and lies along the y axis within a uniform magnetic field, \vec{B} = 1.90 \hat{k} T. If the current is in the positive y direction, what is the magnetic force on the section of wire?

Consider a monopoly that produces a single good. The inverse demand for the good is p = A - bQ where Q is the monopoly’s output, p is the price, and A and b are positive constants. The cost of producing the good is C(Q) = Q^2 / 2. (a) Solve for the monopoly quantity. (b) Given your answer to part a, what is the monopoly profit and what is consumer surplus? (c) What happens to the monopoly price and profit when A increases? What is the intuition for the answer (hint: what happens to the elasticity of demand when A increases? What happens to the price and to the monopoly profit when the elasticity of demand changes?) (d) Compute the welfare loss due to monopoly pricing and examine how it varies with A and b. Can you provide an intuition for your result? (e) Given your answer to part a, what is the deadweight loss? (Hint: notice that the deadweight loss is the area between the demand function and marginal cost for all units from the monopoly output up to the quantity at which demand equals marginal cost). Please provide a detailed answer.
