What is the logic behind the IRS permitting a plan to be integrated with Social Security? The presence of the taxable wage base robs HCEs of potential employer matches into the Social Security system. Most retirement legislation benefits the HCE population. This is designed to offset employee procrastination.

Problem 27: This problem involves plotting a phase diagram for mixtures of poly(isobutylene) (PIB) and 1,4-poly(butadiene) (PB) in the melt state. For simplicity, assume equal molecular weights and monodisperse polymers, M_(PIB) = M_(PB), and a common density of ρ = 0.87 g/cm^3. 1. Determine the molecular weight required to place the critical temperature at 100°C. 2. Calculate the spinodal (stability) curve and plot this on a figure with 25°C < T < 125°C. 3. Calculate the binodal (equilibrium) curve and include this in the phase diagram. Hint: This problem is easily completed using a numerical solution for Δ(G_m)/Δ(φ_i) based on the symmetric form of ΔG_m.

Measuring stellar masses. The spectral lines of 2 stars in a binary system shift back and forth with a period of 2 years. The lines of star 1 shift twice as far as the lines of star 2. The Doppler shift indicates an orbital speed of 100,000 m/s for Star 1 relative to star 2. What are the masses of the 2 stars? Use Newton's version of Kepler's 3rd law: p^(2) = (4π^(2))/(G(M_(1) + M_(2)))a^(3) And the relationship between the velocity of a star (v) and its orbital period (p): v = 2π(a)/p Where the radius of the orbit is represented by (a)

L. Ductile Material Assume that both bars are made of AISI No. 1030 Heat Treated Steel with Q&T (Quench & Tempered), heated and cooled to strengthen the materials at 800Â°F. Find the value of the force F that is required to initiate yielding. Case A: P = 0 (Example 5-3) Case B: P = 200 lb (Investigate the point at the tension side of the beam) Case C: P = -200 lb (Investigate the point at the compression side of the beam) II. Brittle Material Assume that both bars are made of ASTM grade 25 cast iron. Find the force F with Modified Mohr failure model. Case A: P = 0 (Example 5-5) Case B: P = 200 lb Case C: P = -200 lb Homework 2: This problem is modified from Problem 5:36. Refer to Example 5.4 as well. The problem figure is given below. Problem 3.1: Find the deflection vector at the free end of the cantilever beam, including the deflection along the x and z-axes and rotation with respect to the x-axis due to torsion T. The forces are given by F = 0.55 kN, P = 4.0 kN, and T = 25 N-m. No need to work on deflection assignment for HW3. Problem 3.2: The material is a ductile material, AISI 1006 cold-drawn steel. Compute factors of safety based upon the distortion energy theory (i.e., based upon the von Mises stress) for stress elements at Point A only of the member shown in the figure. The forces are given by F = 0.55 kN, P = 4.0 kN, and T = 25 N-m. Problem 3.3: The material is a brittle material, ASTM grade 25 cast iron. Compute factors of safety based upon the distortion energy theory (i.e., based upon the von Mises stress) for stress elements at Point A only of the member shown in the figure. The forces are given by F = -0.55 kN, P = -4.0 kN, and T = 25 N-m.

(Calculating the expected NPV of a project) Management at the Doctors Bone and Joint Clinic is considering whether to purchase a newly developed MRI machine which they feel will provide the basis for better diagnoses of foot and knee problems. The new machine is quite expensive and will be used for a number of years. The clinic's CFO asked an analyst to work up estimates of the NPV of the investment under three different assumptions about the level of demand for its use (high, medium, and low). The CFO assigned a 50 percent probability to the medium-demand state, a 30 percent probability to the high state, and the remaining 20 percent to the low state. After making forecasts of the demand for the machine based on the CFO's judgment and past utilization rates for MRI scans, the following NPV estimates were made: a. What is the expected NPV for the MRI machine based on the above estimates? How would you interpret the meaning of the expected NPV? Does this look like a good investment to you? b. Assuming that the probability of the medium-demand state remains 50 percent, calculate the maximum probability you can assign to the low-demand state and still have an expected NPV of 0 or higher. (Hist. The sum of the probabilities assigned to all three states must be 100 percent.) a. The expected NPV for the MRI machine is S. (Round to the nearest dollar.) Data Table Demand State Probability of State NPV Estimate Low 20% $(300,000) Medium 50% $200,000 High 30% $400,000 Print Done
