Detail design a gear reducer that would meet (at a minimum) the following design specification:

• Power to be delivered: 40 hp
• Input speed: 1750 rpm
• Output speed: 40–44 rev/min
• Usually low shock levels, occasional moderate shock
• Input and output shafts extend 4 in outside gearbox
• Maximum gearbox size: 18-in x 18-in base, 36-in height
• Output shaft and input shaft in-line
• Connection to a roller and conveyor via a chain drive

Other than the reducer design, design the intermediate and main shafts, including complete specification of the gears, bearings, keys, retaining rings, and shaft.

Briefly describe how a Photovoltaic cell (PVC) operate and generate electrical power. Support your answers with schematic sketches if necessary

Describe briefly what are the basic planning and design factors when applying “Escalator”?
Sketch the general layout and the main dimensions of an escalator inclined at an angle of 30o

The following details refer to a centrifugal pump. Outer diameter: 36 cm. Eye diameter: 18 cm. Blade angle at inlet: 28°. Blade angle at outlet: 20°. The flow velocity remains constant at 10 m/s. The whirl at inlet is zero. the manometric efficiency is 95%. If width at outlet is 3 cm, determine the power in W (η₀ = 83%).

A Rankine power cycle with reheat uses water as the working fluid. The inlet conditions of the
first stage turbine are 14MPa and 600C. All the turbines are known to have isentropic
efficiency of 85%, however the pump is assumed as an isentropic pump. If the maximum
temperature is kept at 600C and the condenser pressure is 6 kPa, by constructing a suitable
plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three
reheat pressures between 2 to 12 MPa)
Note: You may construct the plot on Microsoft Excel or manually on a graph paper. However,
all the calculations involved must be performed manually, in details and must be shown clearly.

please read the article 'Exley Chemical Company' and write what was the type of organization in the company? do you think the company should be organized in other ways ?

explain in the Fortran 77 code performance evaluation of evaporative cooler with corrugated fins and spherical fins...

mention it's parameter in Fortran 77 and plot graph using fortran 77

skip it.....if u can't answer it.....

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.
