1. HISTORICAL BACKGROUND OF TCDSCo Transport consulting design share company (TCDSCo) is a full fielded state owned consulting firm that deals with the design and construction supervision of road‚ bridges and airports. The company is established in august 1987. Before its establishment as an independent consulting firm TCDSCo had been a division under Ethiopian roads authority. The main purposes of its establishment are the following:- To engage in the activities of surveying and designing of

B. the fire retardant is intended to occur at temperatures higher than those developed in fires C. all chemicals used as fire retardants can be used for exterior applications D. fire retardant treatment of wood increases its strength 2. Most fire-retardant chemicals operate by: A. accelerating the absorption of moisture toe extinguish flame spread B. combining chemicals with air to eliminate the air supply C. accelerating the formation of charring in the wood D. increasing

There are three types of stress‚ they are: (i) Tensile stress (ii) Compressive stress (iii) Shear stress Strain‚ e is defined as the extension per unit length. Strain‚ Where = extension/elongation = original length There are two types of strain‚ they are: (i) Tensile strain = = (ii) Compressive strain = = Strain is the ratio of the change in length to the original length

Design of Waste Heat Boiler 1.00 Introduction: It is a High Pressure & High Temperature exchanger to transfer heat from synthesis gas of Ammonia and generate high pressure steam from boiler feed water. Such exchangers are being designed as per International Codes viz. ASME Section VIII‚ Div-2 an American code or AD Markbleter a German code. Since it is generating steam on shell side‚ the shell is also to be designed as per IBR (Indian Boiler Regulation) code. In India and other foreign

OBJECTIVE To ensure and guarantee the safety of flight‚ the materials in an aircraft used is an important element. This includes small parts like nuts‚ bolts and screw. The materials are chosen because they must have a certain features like light and extremely strong This project looks into the parts of an airplane mainly the wing. The wing of an aircraft comprises of skin‚ spar‚ ribs and stringer. We will further discuss into the properties‚ test standards and factors of the materials being chose

Today in this report I will explain how the forged hook is better compared to a cast hook. My reasons towards this decision are later discussed throughout this report. Forging is referred to as the shaping of a metal through the use of compressive force; forging can be classified as hot or cold and will be explained later in the report. Casting is referred to as when a liquid metal is poured into a desired mould‚ cooled then removed. Both of these manufacturing processes have their own benefits
