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 normal and shear stresses and their plane of
orientation.
c. If the yield strength of the material is 350MPa, Poison’s ratio is 0.32, and factor of
safety is 5, determine the diameter of the shaft to avoid failure.
d. What will be the difference in the analysis above if there is an additional torsional
load (T) and bending moment (M).
e. Show how you can use any theory of failure to design this shaft.
f. What are the challenges of applying the theories of failure in actual engineering
practice and as a design engineer, how would you deal with these challenges.

Case study Description Faisal is a successful architect who is trying to use the extra time that he has during the coronavirus crisis in a simple way. He decides to focus on an ambitious new project. In this project, he and his team of architects, engineers, and developers will build a house specifically for living on the sea. It will be stable and safe in waves up to five meters high. A family of five will be comfortable living in it. Faisal and his team decide to make the house simple but beautiful. Since real estate can be expensive, Faisal decides to make the house cost less than USD 400,000. There will be a dock that will be attached to it which can lift boats out of the water and automatically wash them, in order to keep them from rusting. To make it so that it could float in areas close to cities in the Arabian Gulf, the house is designed so that it does not need water any deeper than two meters deep in order to be stable and floating. To help the family to be able to travel back and forth comfortably to their floating home in any type of weather, Faisal offers a special boat that can handle high waves.

Explain which methods of simplicity have been applied in this case study. Mention at least 3 different methods and provide clear reasons for choosing these methods.

At atmospheric pressure, moist air at T1 = 35°C and 40% relative humidity enters a heat exchanger operating at steady state and is cooled at constant pressure to 24°C with a m with dot on top of 11 kg/min. Ignoring kinetic and potential energy effects, determine: (a) Properties at state 1: (10 points) Mixture enthalpy, Humidity ratio (b) Properties at state 2: (15 points) Mixture enthalpy, relative humidity, humidity ratio (c) the dew point temperature at the inlet, in °C (5 points) (d) the rate water is condensed (5 points)
