TRUE or FALSE? (Write T or F in the space provided) 60 Points 1. Young’s modulus is a measure of stiffness of the material ( ) 2. Metals are examples of non-crystalline materials. ( ) 3. Tool life increases when the cutting speed is decreased. ( ) 4. Positive rake angle causes low values of shear plane angle, greater chip distortion and produces rougher and more work hardened surfaces. ( ) 5. The principal applications of the WC and Co are in the manufacturing of carbide tools. ( ) 6. Given that a round workpiece of 0.5” diameter is rotating at 300 rpm during turning, the approximate linear cutting speed is about 39 ft/min. ( ) 7. High value of surface finish indicates a better, smoother finish. ( ) 8. High yield strength materials are expected to give low spring back in bending. ( ) 9. A face plate is used to grasp irregular shaped parts in a lathe. ( ) 10. Danner process is used to make glass tubes. ( )

Simple enough. So, look at this example: From $1 Million to $1.05 Million (this is a 5% increase in sales, you see that, right?) (DM, DL, and OH): From $900K to $945K (5% increase in your costs, you see that, right?) (Revenue COGS): Was - $100K ($1M - $900K = $100K in profit) Now - $105K ($1.05M - $945K = $105K in profit) = (5% increase in profit from a 5% increase in sales) More simply stated: $1 Million $1.05 Million (5% increase): $900K $945K (5% increase): $100K $105K (5% increase) However, reducing Costs of Goods Sold (COGS) is much more powerfulWhat would these answers be if you cut COGS by 5% and sales did not change (fill in the question mark blanks below)?Homework Section:: $1 Million (No change), here are the 5 HW blanks (cut this by 5%): From $900K to $_____?K (5% reduction in COGS = $___?K): Goes from $100K to $_____?KThats a _____?% increase in profit from your original $100K in profit! I would need _____?% more sales to increase my profit by that much. Hint, the answer for the last two blanks is the same.

2. (40 point total) A lossless, air dielectric transmission line is 0.75 meters long and has a characteristic impedance of 50 ohms. The line operates at a frequency of 300 MHz and is terminated in a load impedance $Z_L = 50 + j10$ ohms. (a) (10 pts) Sketch and label a circuit diagram showing the transmission line, load impedance and indicating the input impedance, $Z_{in}$, to the terminated line section. Include relevant information given above in this sketch. (b) (10 pts) Find the complex load reflection coefficient for this line in rectangular form? (c) (5 pts) Find the wavelength in meters on this line. (d) (15 pts) Find the input impedance, $Z_{in}$, in rectangular form, for this line.

Suppose we want to transmit the message 11011101 and protect it from errors using the CRC polynomial x^4 + x^3 + 1. Use polynomial long division to determine the message that should be transmitted. Show the CRC computation done at the receiver in case of no errors. Suppose the leftmost bit of the message is inverted due to noise on the transmission link. What is the result of the receiver's CRC calculation? How does the receiver know that an error has occurred?
