So what is the basic definition of Mechanical and Electrical Systems? In addition, what does the word "energy" mean?

For each of the MAJOR components (6.1, 6.2 and 6.3) stated only, analyze and identify the manufacturing processes used to make the component – both primary (bulk shape forming) and secondary (or finishing) processes. Include sub-sub-section as follows for each component:

o 6.1.1 Component Observations: Describe your observations of the physical component which indicate what manufacturing processes were performed. Include an annotated picture with arrows pointing to the features.

o 6.1.2 Manufacturing Process: With supporting literature and research, describe the chosen manufacturing process concisely in detail, noting its advantages and disadvantages – describe it in the context of the gearbox you are looking it, not just generally. Detail the advantages and disadvantages of these processes: Relate the chosen method to the production volume of the gearbox.

o 6.1.3 Material Relationship: Relate to the material and its appropriateness in this manufacturing method (e.g. does it have suitable castability?)

A rail-gun fires a tungsten projectile horizontally with an exit muzzle velocity of 1500 m/s. The horizontal acceleration of the projectile is given as ax = -40vx^2 + 125000vx - 96900000 where vx = horizontal velocity. The muzzle is 50 meters off the ground. At what distance, in meters, from the muzzle will the projectile strike the ground if the ground remains level? Do not neglect the effects due to gravity.

Please help, I don't understand how to do this problem since acceleration in the x direction is not constant.

4- If the drag force on a smooth sphere depends on the velocity (V), sphere diameter (D), viscosity (?), and density (?), use dimensional analysis to show the drag coefficient on the sphere is a function of the Reynolds number only. (15%) ?

What is the purpose of a throttling valve? What are the implications of having a throttling valve prior to the pump inlet? Explain in terms of NPSH. i.e. what will happen if the valve is placed before the pump? or why do we put the valve after the pump instead of before the pump.

A seismic instrument (a mass connected to a spring and a damper) is employed to record a periodic input signal y(t)=0.5cos(15?t), where y = displacement [cm], t = time [sec]. The damping ratio of the instrument is 0.6. Select a combination of mass, spring constant, and damping coefficient to yield less than a 5% amplitude error in measuring the input signal.

Consider 50 moles of carbon dioxide in a piston-cylinder that is isothermally compressed at temperature of T=350 K from 100 kPa to 400 kPa. What are the changes in the total entropy (of the Universe), the system, and the surroundings if the gas is compressed using a heat reservoir at a temperature of 350 K? Using a heat reservoir at a temperature of 250 K? You can assume that the processes within the piston-cylinder system are internally reversible.

10–15E A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 2500 psia in the boiler and 5 psia in the condenser. What is the minimum temperature required at the turbine inlet such that the quality of the steam leaving the turbine is not below 80 percent. When operated at this temperature, what is the thermal efficiency of this cycle?

Design an HVAC system for an office building. All of the offices should be maintained at 72°F.

Model a corner office, 6m by 6m and 2m high. Make the exterior walls glass and the interior walls are drywall at the ambient temperature. Model a cold winter day as -5°C with a 10 m/s wind and a hot summer day at 40°C with a 4 m/s wind. Model a person as a 37°C vertical cylinder with 1 m² surface area 170 cm high. Ignore heat transfer to the top of the cylinder.

Include convection and radiation. The person is losing heat by natural convection to the environment at its ambient temperature (27°C) and gains or loses heat by radiation to the windows. The window temperature will be at whatever the steady-state conduction temperature is assuming natural convection on the inside and forced convection on the outside. The window is 1 cm thick glass with thermal properties of ordinary window glass. The area affected is only half the person’s surface area.

Compute the radiation loss or gain for the person and the total heat loss from the person in each season

An ideal gas is contained in a piston-cylinder device and undergoes a power cycle as follows: 1-2 isentropic compression from an initial temperature T1 5 208C with a compression ratio r 5 5 2-3 constant pressure heat addition 3-1 constant volume heat rejection The gas has constant specific heats with cv 5 0.7 kJ/kg·K and R 5 0.3 kJ/kg·K.

Design a Turing Machine to construct the function f(n) = 4 [1/4 n] + 2, (that is, 2 more than 4 times the integer part of 1/4 n) for n Element N. Do not just produce a TM, but also describe briefly how it works. There is a TM in the Cooper notes that does something similar. You may modify it to produce the required TM, or produce a machine totally independently.

Anisotropy frequently occurs in materials. Suggest how this anisotropy might occur
(hint: consider manufacturing processes) and how a knowledge of the level of anisotropy
might be important when designing components. Use polymer shopping bags as an example. Can anisotropy be “useful”?
