Pavement performance is an important factor in pavement design because it provides a framework upon which a judgement on the road is either success or failure, which is associated with the ability of the pavement to carry out the design loading. Based on these statements, briefly discuss a distinction between the two different types of failures.

The shorter legs of two 6”x 4” x 1⁄2” angles are welded
to a 12”-20.7-lb channel. Determine the moments of
inertia of the combined section with respect to
centroidal axes respectively parallel and
perpendicular to the web of the channel.

When answering the following questions, explain the relationship to critical infrastructure protection.

Describe five of the 11 transportation infrastructure in terms of risk and protection - roads, railways, walkways, bridges and tunnels, stations, airports, air routes, waterways, ports, cycling infrastructure, and living streets.

Non suspended slab and suspended slab.What is the difference in details? Where is the location? What is the challenge to build it?

Explain the construction of both slab step by step in details.

Immediately after a fill is placed, the excess pore water pressure in an underlying saturated clay is equal to:

a. 0

b. 100 lb/ft2

c. The hydrostatic pore water pressure

d. The unit weight of the fill times its thickness

e. Half of Δσ_z

The study of the mechanics of solids is a central object in the formation of various engineering modalities. And it is not for nothing that it is mandatory discipline in almost all engineering. Almost every concrete human achievement (not just intellectual or virtual), be it a building, a machine, equipment or even a (plastic) work of art, needs a structural support, something that can perform its function mechanically .... (José Roberto de F Arruda). 

Given the great importance of solid mechanics in Engineering, cite and comment on 3 examples of the application of Solid Mechanics in our daily lives, and their importance in solving engineering problems.

Case study: TBS Shipping

1. Assuming the MV Hamburg Pearl has a DWT of 44,500 MT, an empty weight of 6,500 MT, and a crew, stores, and fuel weight of 1,000 MT, estimate how much of the following will fit into the cargo holds, without exceeding the ship's volume or weight limits:

Sunflower seeds: Blank 1 MT
Cobalt: Blank 2 MT
Peanuts (unshelled): Blank 3 MT

To answer this, you will need to look up standard values for stowage factors and calculate the answers. If you find the stowage factor is a range, use a value in the center of that range.

2. Why do you think the problem with the wood pellets happened without being caught ahead of time? Use your own words to explain the basic reason in a sentence or two.

3. What would you do to protect against this problem happening again?

The wastewater treatment plant will also treat wastewater originating from the industrial activity of textile mills in the future. proposed and describe appropriate unit processes that can be added to the plant.

During a chemical treatment of wastewater the reaction rate found to be 20.8 /minutes when the temperature of wastewater was 29.4°C. What will be the reaction rate when the same reaction is performed in the evening when temperature reduced to Y °C. The value of temperature coefficient is 1.130

NaOH + FeCl_{3 >}    Fe(OH)₃ + NaCl

Morrison claims that the building of the Middlesex Canal can be seen in one of two ways: (1) "a continual and almost systematic botching of a very simple process"; or (2) "as an exercise rather more remarkable than [landing a man on the moon]" (Page 29). Which interpretation do you consider more accurate, and why? Use three examples to explain your argument.

what is a runoff coefficient in hydrology and what is hydrologic abstraction?

what is their use and why do they matter in the engineering world?

What are the primary strengths or weaknesses of the concept?

What would have made it easier for you to understand the method or concept?   

Rod OA rotates counterclockwise with a constant angular velocity of = 5 rad/s. The double collar B is pin connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r = 1.5(2 - cos θ) ft. If both collars weigh 0.75 lb, determine the normal force which the curved rod exerts on one collar at the instant θ = 120^o. Neglect friction.
