Once the Mechanic’s evaluation is completed‚ they will replace or repair any deteriorated or defective parts. A Mechanic also evaluates and services various other parts of an aircraft‚ including: repairing sheet metal or composite surfaces measuring control cable tension looking for and evaluating corrosion‚ distortion‚ and cracks in

available are Wooden‚ Aluminum‚ and fiberglass. Wooden ladders are heavy and hard to keep clean. Wooden ladders are sturdier than fiberglass or aluminum ladders and can be used when heavy loads must be moved up or down the ladder. Aluminum ladders are corrosion-resistant and can be used where ladders might be exposed to weather. They are light weight and can be moved easily for different locations. You should never use aluminum ladders around electrical hazards‚ such as energized electrical conductors or

silvery grey metal. Vanadium was discovered by Andrés Manuel del Río‚ a Spanish-born Mexican mineralogist‚ in 1801 [1]. Some sources say Vanadium is soft because it is ductile [1]. Vanadium is harder than most metals and steels [1] It is resistant to corrosion and it is stable against alkalis‚ sulfuric and hydrochloric acids[1]. It is oxidized in air at about 933 K (660 °C‚ 1220 °F) [1]. This paper will discuss the effects of Vanadium on the environment and Vanadium’s properties. Chemical Properties:

Introduction of Ceramics What is Ceramics? A ceramic is an inorganic‚ non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure‚ or may be amorphous (e.g.‚ a glass). Because most common ceramics are crystalline‚ the definition of ceramic is often restricted to inorganic crystalline materials‚ as opposed to the non-crystalline glasses. The word ceramic comes from the Greek word "κεραμικός" (keramikos)‚

[1‚ 2] Increased demands from modern automotive systems have necessitated the use of these new technologies to give such improved properties as increased load handling‚ longer lifetimes and corrosion resistance to name but a few. Engines in particular have received much attention. The engine and its components alone contribute to 15 percent of the total frictional losses in the vehicle. Aluminium alloys have more recently been preferred to cast

1. OBJECTIVES‚ FUNCTIONS‚ TYPES AND ECONOMICS OF MAINTENANCE MAINTENANCE OBJECTIVES: The objectives of maintenance are to ensure the desired plant availability at an optimum cost within the safety prescription. In otherwords‚ it may be mentioned that the objective of maintenance is to minimise the total cost of unavailability and resources. Whenever the plant is not available either due to breakdowns or due to planned stoppages‚ the following costs are incurred. 1) Loss of earnings due
