R1 Rf V1 O R2 V20 R3 + V3 O Vo Figure 1: Summing Op Amp Schematic. 1. Given the circuit shown in Figure 1 with Rf = 47k\Omega, solve for the resistance values R1, R2, and R3 so that the output Vo satisfies the following relationship: Vo = $-2.14V1 + 1.00V2 + 0.47V3$ (1) 2. Draw the output waveform Vo for the input waveforms V1 and V2 shown in Figure 2 with V3 = 4.7V. Note: You can do this by hand or by using a simple coding language. MATLAB makes this very simple with functions such as sawtooth for a triangular wave, and square for a square wave. For more help using these functions type \"help\" and the function name into the command line in matlab. 1v- 5 + 5 10 t(ms) 2 1V 2.5 5 10 t(ms) Figure 2: Input waveforms. 3.

b. Interest is 10 percent of weighted-average capital balances. Salaries are $25,100 to Eastwood, $22,000 to North, and $26,000 to West. North receives a bonus of 10 percent of net income after deducting the bonus and her salary. Any remainder is divided equally. Net income was $69,850. (Do not round intermediate calculations. Round the final answers to nearest whole dollar. Amounts that are to be deducted from an individual partner's capital balance should be entered with a minus sign.) Answer is complete but not entirely correct.

3. A tensile stress is to be applied along the long axis of a cylindrical brass rod that has a diameter of 10 mm. If the magnitude of the applied load is 3800 N, determine the change in diameter ($\Delta d$) assuming the deformation is entirely elastic (Modulus of elasticity: 97 GPa). 4. Perform a google search for stiffest material and write a short paragraph (100-150 words) on your findings. Provide the website links you read. 5. A composite is formed by reinforcing a polymer matrix with 30 vol.% continuous ceramic fibers. The moduli of elasticity for polymer matrix and ceramic fibers are 2.4 GPa and 130 GPa, respectively. Assuming that the composite has a cross-sectional area of 325 mm$^2$ and that the composite is subjected to longitudinal load of 45000 N, calculate: (a) fiber-matrix load ratio, (b) actual loads carried by fibers and matrix, (c) magnitudes of stress on fibers and matrix, and (d) strain on the composite.
