5.19 At 8:00 A.M. there are 10 vehicles in a queue at a toll booth and vehicles are arriving at a rate of Ȝ(t) = 6.9 − 0.2t. Beginning at 8 A.M., vehicles are being serviced at a rate of ȝ(t) = 2.1 + 0.3t (Ȝ(t) and ȝ(t) are in vehicles per minute and t is in minutes after 8:00 A.M.). Assuming D/D/1 queuing, what is the maximum queue length, and what would the total delay be from 8:00 A.M. until the queue clears?

This case is a comprehensive engineering ethics case study aims to cover as much as possible of ethical issues to explain how to apply the NSPE code of ethics. In addition, comprehensive case would improve brainstorming and peer discussion.
A young civil engineering student just graduated from college recently. He is specialized in building design and construction. He is hired as a trainee engineer in an engineering office and working with the senior engineer. After working for a few months, he noticed that his projects are not reviewed by the office’s senior engineer and approval directly for construction. This engineer starts to involve with projects designed for large number of people such as schools and public offices. He is worried that he would make a mistake in his designs and kill someone due to un-reviewed projects. He talked to the office manager who informed him that all projects go through second review by the office’s management engineer who uses a software to verify final results.
After a while, the civil engineer was talking to a project contractor who informed him that all engineering office projects are approved by municipality without check due to the senior engineer professional reputation. Moreover, the contractor is given all office projects because of his friendship with senior engineer. The contractor offered him to leave the engineering office and join him for higher salary. This conversion increased the civil engineer even more and put him in a daily concern of what to do in this situation. What the civil engineer should do?
Answer the following question:
1- What are the civil engineer ethical and moral obligations? (9 POINTS – CLO 1)
2- What is the ethical dilemma in this case? (14 POINTS – CLO 2)
3- What are the ethical issues involved in this case? (12 POINTS – CLO 2)
Think of Moral or Ethical issues as:
Actions that have the potential to harm others or help others unfairly.
Any negative impact of project, action, or decision
4- (Ethical Framework): (20 POINTS – CLO 4)
What the civil engineer should do in this case based on NSPE code
of ethics – Use two Canons?
5- (Moral Framework): (20 POINTS – CLO 3)
What the civil engineer should do in this case based on Moral
theories and beliefs (e.g. Utilitarianism,
Virtue Ethics, Duty and Rights Ethics)?
6- (Preventive Ethics): (5 POINTS – CLO 2)
What could be UNETHICAL or IMMROAL behavior in this case (Choose
one)?

The traffic volume in the year 2018 at an airport (number of take-offs and landings) during peak hour of each day is a described as a log-normal random variable with a mean of 200 planes and a standard deviation of 60 planes. a. If the present runway capacity (for landings and take-offs) is 350 planes per hour, what is the current probability of congestion? [2 marks] b. If the mean traffic volume is increasing linearly at the annual rate of 10% of the volume in 2018 with the coefficient of variation remaining constant what would be the probability of congestion at the airport in year 2028? [2 marks] c. Assuming the same projected growth rate of traffic volume as part (b), and that the maximum acceptable probability of congestion is 10% what year will the airport need to increase their runway capacity? [4 marks] d. Assuming the same projected growth rate of traffic volume as part (b) when the airport upgrades their runway capacity in part (c) what new runaway capacity will they need to ensure the probability of congestion does not exceed the max acceptable probability of congestion of 10% until year 2038? [2 marks]

Please provide a step-by-step solution, with "Given:", "Find:", and "Solution:" format, for the problem below. Please be sure to include any tables, values, and references required to arrive at the solution you provide so that the process may be repeated for other values.
Vertical Formwork Design
Given: Design formwork for a 6-ft-high wall. The concrete is to be placed at a rate of 2 ft/hr and will not be vibrated. Concrete temperature is expected to be 50˚F. Use standard weight concrete, Type 1 cement, 3 in slump, with no admixtures. The maximum allowable deflection of bending members is to be 1/360 of the span. Use ¾ in Class I plyform for the sheathing with face-grain across the supports. Use 2x6 Hem-Fir No. 2 for the rest of the lumber and double-wales. Assume all bending members to be supported on three or more spans. Ties available for use have an allowable load of 5000 lb. Show all work.
Find: Design the formwork for this slab.
Solution: Show all your work.

1- what is the formula to find the approximate depth of a concrete slab that measure 180' long X 110' wide (Feets)?
[[let said that I have two of them (same length and wide, and one have have 4" thickness and the other 6" (inches)? ]]
2. What types of concrete slabs are better to use in residential, commercial, and one story store buildings?
please explain clearly, thank you.
