Task 1 - Properties and use of construction materials (LO1)
You have been asked by your managing director to put forward to present at a young professionals conference organised by the CIOB. You have to submit the following essay to the organisers for final selection.
A 1500 word limit to provide your opinion on one of the following statements:
1. Steel is by far the most suitable material to use for the structure of a building.
You are to provide your opinion on your chosen statement and provide evidence to substantiate it.
The work must be in an essay format, not a report. You must present the work correctly. There must be a combined reference/bibliography and use correct referencing and quotations when required.
Two identical uniform boards, each of weight 40lb, are temporarily leaned against each other. Knowing that the coefficient of static friction between all surfaces is 0.40
Discuss some of the impact/ importance of the solutiongenerated and how these solutions have improved over time
The current removal efficiency is 96% for an air flow rate through the separator equal to 18 m3/s. Due to a process change, the air flow rate is expected to increase to 22 m3/s.
Offshore oil exploration platform is expected to encounter current of 3 m/s wave height 4 m and periods 15 seconds. A 1 in 20 scale modes is to be build and tested in hydraulic laboratory to determine the forces on the full scale structure.
If the farmer irrigates continuously, what will be the steady-state concentration of selenium in the stream downstream from the farm (after the irrigation run-off returns to the stream)?
A truck is traveling down a road with a 3-percent grade at a speed of 55 mi/h when the brakes are applied. Knowing the coefficients of friction between the load and the flatbed trailer (us= 0.40) and (uk= 0.35)
If the tangents intersect at an angle of 40 degrees, what is the highest degree of curve that can be used?..how to solve this problem using chord basis formula?
The man has a mass of 65kg and stands motionless at the end of the diving board. If the board has the cross section, determine the maximum normal strain developed in the board. The modulus of elasticity for the material is E = 117GPa
of 2640 psi with a factor of safety of 2.0 with respect to yielding. the yield stress of the steel is 65,000 psi in tension and 32,000 psi in shear. the diameter of the tank is 7.0 in. the minimum required wall thickness is 0.289 in.
A 1047 steel plate is subjected to a tensile stress of 120 MPa. Given its fracture toughness is 45 MPa?m and Y = 1, (a) Determine the critical crack length to assure the plate will not fail under static loading.
An aeration system with a hydraulic retention time of 2.5 hours receives a flow of 0.2 MGD with BOD concentration of 150 mg/L. The suspended solids concentration in the aeration basin is
