Le Corbusier was fascinated by certain engineering objects. This interest was well expressed in his book Towards a new Architecture (1923) and well captured by his definition of house as “a machine for living in”. In a similar vein, Walter Gropius outlined the new orientation of his school as “the Bauhaus believes the machine to be our modern medium of design and seeks to come to terms with it.”

What do these two statements mean? What is the relation between ‘architecture’ and ‘machine’ as stated by these two architects? Explain your answer by using at least one building by Le Corbusier and one building by Walter Gropius.

1.Under the lockout/tagout standard, what is the difference between an authorized employee and an affected employee? Include the citation for the OSHA standard where you found the answer to the question.

2.Other than the color, what is the difference between "Danger" signs and "Caution" signs? Include the citation for the OSHA standard where you found the answer to the question

Let's just say some random guy approaches you on the street asking what an "influence line" is. He claims to be a structural engineer but has never heard of such a thing. How would you explain it to him? Try to explain in laymen's terms while still appearing competent

2. A wastewater treatment plant discharges an effluent containing 3 mg/L of dissolved oxygen to a river that has a dissolved-oxygen concentration of 6 mg/L upstream of the discharge. The saturation dissolved oxygen for the river is 8 mg/L. Assume that the WWTP discharge rate represents 80% of the river flow rate which travels 0.5 km in an hour. The CBOD5 of the river is 5 mg/L with a decay coefficient of 0.25/day. The reaeration coefficient of the river is 0.5/day. What is the location of the critical point: (a) in time; (b) in distance? (c) Why is critical dissolved oxygen a concern and (d) what are the ways to avoid it?

Design a short square tied column to carry a factored axial load of 1300k and a factored moment of 550kft. Place the reinforcement uniformly around the column. Design the ties. Assume interior exposure, f’c = 4000psi, fy = 60,000psi.

If you needed to reduce deflection in a loaded aluminum rectangular box beam in your structural design, which of the following variables would you INCREASE? :

-Length

-Outer width

-Outer height

-Inner width

-Inner height

Which would be the MOST effective in reducing deflection?

What material could you substitute for aluminum in your design to decrease deflection? Why?

Please explain in detail the effects of different moisture conditions (saturated/dry) in soil to rainfall-runoff relationships? Expound on the concepts of rainfall volume, runoff volume, runoff coefficient, and interflow.

1. what is the quality problem often met in the bored piles with the hole being supported by the mud

2. introduce the different types of the enclosure structure for excavation of basement. what are the advantages and the disadvantages of the steel bracing compared with RC bracing

Circular bars subjected to torsion experience Pure Shear over the cross section. Then, why a classroom chalk subjected torsion experience brittle failure by tension cracking at 45° to the circular cross section? Do some research and explain how shafts made of ductile materials fail when subjected to torsion. Compare and contrast both the brittle failure in chalk and ductile failure in shaft. Explain your answer using the plotted graphs.

Explain with THREE (3) examples of prototypes and their corresponding models flow that have geometric similarity, but not kinematic similarity, even though the Reynolds numbers match.

A chemical company started producing a new chemical which produces cyanuric fluoride (C3N3F3) and diazomethane (CH2N2) as waste products. The process waste stream has a concentration of 200 mg/L cyanuric fluoride and 200 mg/L diazomethane. The flow rate of the waste stream is 1000 L/min. The effluent concentration limit is 5 micrograms/L for both of the waste products. Cyanuric fluoride undergoes a first-order decay at the rate of 0.5 min^(-1), while diazomethane undergoes a second-order decay at the rate of 0.5 L*mg^(-1)*min^(-1). The plant was debating between using a single-stream CMFR or PFR to treat the waste stream. Calculate the required volume for the CMFR and PFR to reach the effluent standards for both of those wastes.
