low carbon steel having a tensile strength of 350 MPa and shear strength of 250 MPa is cut in a turning operation with a cutting speed of 200 m/min. The feed is 0.3 mm/rev and the depth of cut is 4.8 mm. The rake angle of the tool is 12 degrees in the direction of chip flow. The resulting chip ratio is 0.8. Using the orthogonal model as an approximation of turning determine...

f. Cutting power and cutting horsepower.

Thirty-three items are randomly selected from a population of 350 items. The sample mean is 32, and the sample standard deviation 6. Develop a 90% confidence interval for the population mean. (Round the t-value to 3 decimal places. Round the final answers to 2 decimal places.)  

The confidence interval is between  and

EK is a 53 year old male, who weighs 130 lbs, is given a 350 mg loading dose of an anticancer medication. At the same time, a continuous IV infusion is started at a rate of 19 mg/hr. The volume of distribution is 1.4 L/kg and the drug half-life is 7.3 hours. The physician wants drug levels drawn 14 hours after the loading dose was given and the infusion was started. What is the expected plasma drug concentration when the patient's blood sample is collected 14 hours after the infusion began? Note: Assume the infusion is ongoing. Please provide your answer in units of mg/L.\

A 350 mL buffer solution containing 0.15 M HF and 0.150 M NaF is reacted with sodium hydroxide. What mass of NaOH can this buffer neutralize before the pH rises above 4.0? If the same volume of buffer was 0.35 M in HF and 0.35 M in NaF then what mass of NaOH could be handled before the pH rises above 4.0?

a) A machined steel has the following properties: Sut= 400 MPa, Sy= 350 MPa, and S’e= 200 MPa. The value f = 0.9 Sketch the S-N diagram for this material, label the key points on the graph and compute the material strength (Sf) corresponding to 800,000 loading cycles?

b) What value of strength of the materials described above should be used if 3,000,000 loading cycles are expected during the life of this part?

A piston-cylinder device initially contains 0.3 m³ of nitrogen gas at 350 kPa and 35 ℃. An electric heater within the device is turned on and is allowed to pass a 240W for 6 minutes. Nitrogen expands at constant pressure, and a heat loss of 3000 J occurs during the process. Determine the final temperature of the nitrogen. (Average C_P for Nitrogen is 1.039 kJ/kgK and molecular weight of Nitrogen is 28.01 kg/kmol.)

A Carnot engine operates between temperatures of 200 K and 350 K. In each cycle, 4000 J of heat is added to the ideal gas. This engine works on 0.5 mols of a diatomic gas.

A) Calculate the volume ratio for just the adiabatic expansion.

B) Determine the compression ratio - the highest volume divided by the lowest.

C) If you reversed the cycle, how much work would be necessary to pull 100 J of heat from the cold temperature reservoir?
