A high carbon steel shaft is used in an engine and subjected to different loads. In order to analyse the stress in the shaft, consider a rectangular element within the material. This element is subjected to compressive stress of 135 MPa and shear stress of 166MPa in the vertical direction. The compressive stress in the horizontal direction is 176MPa with a shear stress of 115MPa. a. Sketch the state of stress on this element. b. Determine the maximum and minimum...

For what purposes was heroine originally outlawed? Was it for medical or for another reason? Why was heroine nationally outlawed? Today, our country has a greater opiate and heroin addiction problem then before the drug war began. From what you have learned this week, why do you believe the heroine addiction has increased? Are prescription opiates responsible? What has been the impact of this on the nation’s War on Drugs? Since heroine is much cheaper, easier to obtain, and stronger...

Determine what is the temperature of the hot combustion gas that is produced in the engine of a butanol (C4H9OH)-burning bus that uses ambient air for the combustion. Tip: write the balanced stoichiometric equation for the combustion of butanol assuming air is composed of 80% N2 and 20% O2 by volume, and derive the energy balance of the combustion. Atomic weights: C-12, H-1, O-16, N-14. For butanol: cp = 2 kJ/kg/°C; cv = 1.75 kJ/kg/°C; heat released by combustion, or...

15. A reversed Carnot engine (refrigeration unit) is used to maintain the temperature inside a freezer at -34 oC. The room temperature in which the refrigeration unit operates is a constant 24 oC. If the motor on the refrigeration unit uses 0.3 kW, determine the rate at which heat is removed from the freezer in Watts. State your answer in whole numbers. Example: 2147 I WILL RATE YOU
