A highway embankment of formation width of 15 m and side slopes 1.5:1 is to be constructed. The ground level along the centerline is as follows in Table below. The embankment has a rising gradient of 1 in 200, and the formation level at zero chainage is 115.00. Assuming the ground is level across the centerline; compute the volume of earthwork.

: In mechanics, this quantity represents the total area under the stress–strain diagram, and therefore it indicates the maximum amount of strain energy per unit volume the material can absorb just before it fractures. Certainly this becomes important when designing members that may be accidentally overloaded. Which type of modulus is it? Describe it.

c) Use your spreadsheet to estimate the position of the Risk line, using any necessary “reality
checks”. In other words, justify or even make a clear statement of the inadequacies of what
you have done and the need for further investigation. Estimate the Risk value.

Your task is to develop quantified Risk models of two Risks of interest to you. This is an academic
exercise and its purpose is to make you familiar with the process of quantified Risk modelling and
to show me you understand the theory and the practice.
a) Write up each Risk as a case study that explains the Risk in detail and describes the proposed
control measures.

Two types of flow regime are normally used in the design of an activated sludge process,
namely completely mixed and plug flow (both are continuous). Using first order kinetic
reaction, demonstrate which flow regime provide a better performance, given the
followings:
Q = 550 m3/d t = 6 hours Co = 225 mg/L k = 0.15 d-1

1- Use Heun’s method without iteration to solve

?2???2−0.5?+?=0

y(0) = 2 and y’(0) = 0 solve from x = 0 to 3 using h = 0.2 (step size) present y values as a table versus x values (50p)

Instructions about question 1: considering step size and interval for x it will not be reasonable to proceed through hand calculations. You may want to use excel or other software but you need to write down first 3 steps of the calculations (obtain y(0.2), y(0.4) and y(0.6) ) in detail showing all calculations. Rest of the y values can be calculated using a software and tabulated (this is valid for hand calculations too provide calculations for first 3 steps and present the values as a table). You need to provide the code or excel file for the software that you used for calculation.......please sir (with explanation,step by step and calculation)please sir must

Compare and contrast the use of the following three methods of conceptual estimation by researching them:

a. Analogy (top-down) estimating

b. Parametric estimating

c. Heuristic (rule-of-thumb) estimating

1. In California, medical care costs for back injuries are 43 percent higher when part of a workers’ compensation claim than when part of a group medical insurance plan. Critics of workers’ compensation claim that this difference can be attributed to abuse of the system by both injured employees and their physicians. Proponents of workers’ compensation argue that the higher costs indicate exactly the opposite: that is, under workers’ compensation, injured employees are receiving more and better (hence more costly) medical care. They claim that group medical plans are shortchanging employees by allowing insurance companies to make medical decisions. What is your opinion?

2. Following an order from his supervisor, a carpenter working for Jones Construction Company removed all the guardrails from stairwell openings, floor openings, and open-sided stairs. Uncomfortable with this action, the carpenter telephoned his union representative, who, in turn, called OSHA. Jones Construction Company was fined $15,000 for willful violations. Jones Construction Company, in turn, fired the carpenter. Was the firing lawful (under OSHA standards)? Was the action of the carpenter appropriate (under OSHA standards)?
