A skinny billet having a Young's modulus of 50 GPa has a strain with a magnitude of 0.100 generated when 200 MPa of forging stress in applied to make the desired shape. What is the magnitude of the final stress of the part after forging? 0 MPa 0.096 MPa 0.100 MPa 0.104 MPa 20 MPa not enough info

I have some things that need clarification based on the answer provided to this question. Firstly, the h1 value came out as 154.99 kJ/Kg for me not 153.318. Also, the values taken from the steam table for Vf and Vg for 5 degrees celcius and 6 degrees are different from what is on the steam table, I have attached a picture for this. For 5 degrees on the steam table it shows Vf as 0.00100008 and Vg as 147.011 and for 6 degrees it shows Vf as 0.00100011 and Vg as 137.633. Please clarify this and reply as soon as possible. Thanks

17-19. The 50-mm-diameter C86100 bronze rod is fixed supported at A and has a gap of 2 mm from the wall at B. Determine the increase in temperature AT that will cause the rod to buckle. Assume that the contact at B acts as a pin. 2 mm

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

You need to find out the maximum NPV of a hypothetical iron ore open pit as shown below. The iron ore grade is 72% and recovery is 90%. The market price of iron ore is $100/ton. The ore and waste block size are 30 by 30 by 30 m3 and annul production of six blocks (mining + stripping) is there. The mining cost is $35/ton and the stripping cost is $25/ton. The density for the ore and waste is 4.5 ton/m3 and 2.5 ton/m3 respectively. Assuming initial investment $50 million the interest rate is 5% per year.
