Chapter 17, Problem 18P

able to help me with the question below with references too for study purpose   Structural InvestigationThe Building Maintenance and Strata Management Act 2004 interprets “Structural elements,for a building means an internal or external load-bearing component of the building or part ofthe building that is essential to the stability of the building but exclude any door or window.”Loading-bearing components such as wall, column or beam, etc, are subjected to externalforces. (a) Interpret the diagnosis of a structural defect and discuss FOUR (4) external forces ona structure element that may cause structural cracks.(b) Discuss the effects of alkali-silica reaction on concrete structures and formulateFOUR (4) preventive measures.(c) Discuss the differences between chloride attack and sulphate attack on concretestructures(d) Formulate preventive measures to prevent or reduce chloride and sulphate attack onconcrete structures   Hard FinishesNatural timber flooring such as timber strips and…

A horizontal cantilever of effective length 3a, carries two concentrated loads W at a distance a from the fixed end and W' at a distance a from the free end. Obtain a formula for the maximum deflection due to this loading using Mohr's method. If the cantilever is 250 mm by 150mm steel I beam, 3 m long having a second moment of area I as 8500 cm4, determine W and W'to give a maximum deflection of 6 mm when the maximum stress due to bending is 90 Mpa. Take Young's modulus of material E as 185 Gpa.

Aum AA waste incinerator stack emits 27,027 kg/yr of cadmium and has an effective stack might of 100 m. The wind speed is 5 m/s at an anemometer located at 10 m. It is a clear sunny day with the sun nearly overhead (Class B conditions). a. Calculate the ground-level cadmium concentration (in ug/m³) at a distance of 2 km directly downwind? [Refer to tables in the textbook to help with this problem] What is the concentration of cadmium (in µg/m³) inside of a house at the location in part (a) after two hours? Note that the initial concentration of cadmium in the house was zero, there are 0.25 air changes per hour (ach), there is no source of cadmium inside the house, and cadmium is considered a conservative pollutant.
