2. (25 Points) Section A is a steel (E = 200 GPa, \nu = 0.32) tube with an outside diameter of 60 mm and inside diameter of 50 mm. Section B is a solid aluminum (E = 70 GPa, \nu = 0.35) bar with a 50 mm diameter over the first half of its length and 25 mm the second half. Determine the following: [a] Normal stress in section A = 196 MPa [b] Normal stress in section B (middle section) = 134.785 MPa [c] Normal strain in section B (middle section) [d] Change in length of section A = $3.126 \times 10^{-4}$ m [e] Change in diameter of section B (middle section) $\sum F = -65 - 65 + 220 + 45 - F_x = 0$ $F_x = 135.044$ kN

1. A system has impulse response $h_1[n] = 2u[n - 5]$. a) Is this system causal? Explain; b) Is this system stable? Explain; c) Use convolution to determine the output of the system for input $x_1[n] = 2u[n + 1]$; d) Sketch the output, $y_1[n]$ over an appropriate range of n. 2. Repeat problem 1) above for and $h_2[n] = \left(\frac{3}{4}\right)^n u[n]$ $x_2[n] = u[n]$. 3. Repeat problem 1) above for and $h_3[n] = u[n] - u[n - 5]$ $x_3[n] = \left(\frac{3}{4}\right)^n u[n]$.

For all problems where a risk free rate or a dividend yield is given, assume that the interest rate and the dividend yield are annual and continuously compounded rates. Problem 10 A stock index futures price is currently $3100, the dividend yield on the index is 2% per year, and the risk-free interest rate is 4% per year for all maturities. The maturity of the futures contract is 1 year. What is a lower bound for the price of a 6-month European put option on the index futures when the strike price is $3300? What is a lower bound for the price of a 6-month European put option on the index spot price when the strike price is $3300?
