An eye-opening exploration of how social changes such as technological advancements influence the social practices of individuals and nations. For example, your grandparents may have used a dial phone to contact family members and today thanks to technological advancement a majority of persons use a cordless phone or iPhone.In a three paragraph format discuss in your own words the three factors that lead to social change. Include one example of each notion from personal or professional experience in the response.

Then, in a separate paragraph explain how you can apply this learning to a future professional setting. Include a minimum of three points in the response.

Portland cement is a combination of limestone and clay, usually 80-90% limestone, leading to CaO:SiO₂ of approx. 2:1. There are a number of alternative cementitious materials now in use, e.g. slag, which form so-called ‘geopolymer’ pastes.

Find two example of alternative cement materials, compare their composition to that of Portland cement and outline the material and environmental advantages and importance of their use.

An initial geotechnical survey found that the road alignment is situated on a Sandy Clay material

(CL), that is well-drained. What is a typical CBR value to adopt, in -lieu of the final geotechnical survey?

important of form work in construction

The storage in a river reach at a given time is 50000 m3 . At the same time the inflow rate into the reach is 25 m3/s, and the outflow rate is 22 m3/s. Three hours later, the inflow rate is 23 m3/s, and the outflow rate is 22 m3/s. Calculate the change in the storage during the three hours

High Rise Construction

1.) Please discuss the importance of developing building technologies to resist "earth movement, high winds and other lateral forces" in high-rise construction.

2.) Examine relevant techniques and other factors such as "building load and height" issues in structural design and support your points with some examples. I am particularly looking for relevant technologies that are in use today to help compensate for these factors in construction.

What is the "C" value (Rational method) for a playground with a 3% grade and a 50 year design storm frequency?

List and briefly describe different risk treatment responses?

this is a risk analysis question.

A concrete slab, 40 ft. long, 11 ft. wide, and 9 in. thick, is placed on a subgrade having a modulus of subgrade reaction of 200 pci. A 9000-lb single-wheel load is applied on the edge of the slab over a circular area with a contact pressure of 100 psi. Determine:

1. The maximum tensile stress due to the 9000-lb wheel load;
2. The curing stresses (both x and y directions) at the edge during the night when the temperature differential is 13.5°F per inch of slab. (Note: the total temperature differential should multiply slab thickness.)

Use the information: modulus of elasticity of concrete = 4×10⁶ psi, Poisson’s ratio of concrete = 0.15, coefficient of thermal expansion of concrete = 5×10^-6 /°F.

Question 2

An outcome of at--site flood frequency analysis is the confidence limit~ on the predicted peak flow of the flood hydrograph, Qiscuss whether similar flood characteristic prediction Obtained using regional methods (for exampte,Probabilistic Rational Method) should also have confidence limits.
