Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose

ASPECTS OF MATERIALS CONTROL The main aspects of materials control are the physical control or safeguarding of materials. Physical control protects materials from misuse or misappropriation. Maintaining an appropriate level of raw materials inventory is one of the most important objectives of materials control. An inventory of sufficient size and variety for efficient operations must be maintained‚ but the size should not be excessive in relation to scheduled production needs. Every business requires

mechanical deformation process of different materials by three tests: tensile test‚ impact test‚ and fracture-toughness test. The materials evaluated in the tensile test were annealed 1045 steel‚ cold rolled 1045 steel‚ 2024-T4 aluminum and cast iron. 2024-T4 aluminum is concluded to be most ductile (25.7 % reduction in area) and cast iron the most brittle (123 MPa). Effects of cold rolling in 1045 steel are apparent‚ as it has the highest strength among the materials tested (402 MPa yield strength). Impact

It has recently been found that material hardship impacts the development of a child. Specifically‚ authors Huang and Sherraden (2016) found that material hardship has a negative association with the social-emotional development of young children. Although it is generally known that different aspects impact the physical and emotional development of children‚ it is unclear as to which have a direct effect on a child’s brain development. To be successful in life‚ the development of all areas in the

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

Uniform at University This essay will examine the positive and negative aspects of wearing university uniform. University uniform is implemented at some universities in the world. The universities of Kurdistan Region do not implement it. Uniform has both positive and negative aspects. Everyone has his/her own point of view about university uniform. Some people think that aside from positive aspects of uniform; it also has negative aspects. The positive aspects of wearing university uniform can
