Civil Engineering Question

Designing a structure that is safe and meets all the necessary building codes and regulations involves several steps. Here are some key considerations:

  1. Identify the building codes and regulations that apply to your project: You need to be familiar with the codes and regulations that apply to your project, which can vary depending on the location, size, and type of structure.
  2. Determine the structural requirements: You need to determine the structural requirements of your project based on factors such as the intended use of the structure, the expected loads, and the environmental conditions.
  3. Select appropriate materials: You need to select appropriate materials based on the structural requirements and other factors such as cost, availability, and sustainability.
  4. Design the structure: You need to design the structure to meet the structural requirements and building codes and regulations, using appropriate software and tools.
  5. Obtain necessary approvals and permits: You need to obtain necessary approvals and permits from local building authorities before beginning construction.
  6. Conduct inspections during construction: You need to conduct inspections during construction to ensure that the structure is being built according to the approved design and meets all the necessary building codes and regulations.
  7. Test the structure: You need to test the structure after completion to ensure that it meets all the necessary safety and performance requirements.
  8. Maintain the structure: You need to ensure that the structure is maintained properly over its lifetime to ensure continued safety and compliance with building codes and regulations

Aerospace Engineering Question

A Boeing 737-300 needs to take off from a runway. At t=0 the pilot is waiting for the signal from the control tower. Wheel friction is not taken into account. Check with known flight performance data.

With all conditions given; show whether the runway is long enough for the aircraft to take off. Elaborate on the length runway needed. Beware of the dimensions!!

Questions

DISCUSSION ESSAY

Provide an original answer, the ones on other homework help websites are incorrect.

Oil Coating: A long, continuous belt is pulled upwards through a chemical oil bath at velocity V0. The belt has rectangular cross-section and has length (L), width into the paper (W). The belt picks up a film of oil of thickness h, density ρ, and dynamic viscosity μ. Gravity g tends to make the oil drain down, but the movement of the belt keeps the fluid from running off completely. Assume fully developed, steady, laminar, incompressible and two-dimensional flow of oil to answer the following questions. Assume that no pressure gradient is needed in the vertical direction to drive the film flow. Also assume that the shear stress at the air-oil interface is zero (free shear condition). Assume no-slip condition for the fluid in contact with the moving belt. Justify any other assumptions you may make. Show all steps.

(a) Derive an expression for the two-dimensional velocity field inside the oil film in terms of the known parameters. Clearly indicate your co-ordinates and origin. You must indicate which equations are used, which terms in your equations vanish (with proper justification), and what boundary conditions are applied.

(b) Sketch the velocity profile in a non-dimensional form as v/V0 versus x/h.

(c) Derive an expression for the volume flow rate of the oil film.

(d) Calculate the velocity (non-zero) of the belt (Vcritical) at which there is no net oil flow.

(e) Calculate the shear stress, if any, on surface AD of the fluid element ABCD inside the oil film. Indicate the direction of the stress and whether it is positive or negative.

(f) At some point X(x0,y0) inside the oil film, calculate an expression for the total acceleration (magnitude and direction).

Electrical Engineering Question

An engineering firm realizes that a new machine will be needed in seven years. The new machine is expected to cost $2,589,000, at current cost, however, the machine is very popular, and supply has been limited, therefore, the price escalates by 5% each year. The firm expects interest rates to be 2.5% for the next seven years with no variation anticipated. The Chief Engineer would like to know how much money the firm would have to accumulate at the end of each year over the next seven years to be able to pay cash for the machine.

  5. You are the project manager for a very important e-learning project that will add 25 identical web portals for the separate divisions of a large, international company. Although some differences in the web portals exist, for planning and execution purposes, the portals are considered to be identical. The plan requires the entire team working on and completing a web portal before beginning the next web portal. Your team has completed the planning process and is in the middle of executing the project. Web portal priorities have been established and agreed to by all stakeholders. Therefore, the most time critical web portals are started and completed first. Your budget baseline allows $255,000 to complete each web portal. You are conducting a team progress review at the end of the 15th week of the project. You find out that the Earned Value is$1,020,000 and the Actual Cost is $1,189,000.
  1. The team has been able to implement the plan with some difficulties. Based on the information provided, how many web portals has the team implemented by the end of the 15th week?
  1. What is the EV at the end of the 15th week?
  2. What is the CV at the end of the 15th week?
