This can be done by the use of instructional materials. Instructional materials are meant to stimulate pupils’ interest in the classroom for meaningful learning to take place. They also afford the pupils the opportunity to make use of more of their senses in the process of learning experiences which are not available in the classroom or school environment‚ are “brought” to the classroom for pupils’ attention through the use of instructional materials. For example‚ the use of the map of the world

“SMART MATERIALS” ABSTRACT The world has undergone two materials ages‚ the plastics age and the composite age‚ during the past centuries. In the midst of these two ages a new era has developed. This is the smart materials era. According to early definitions‚ smart materials are materials that respond to their environments in a timely manner. The definition of smart materials has been expanded to materials that receive‚ transmit or process a stimulus and respond

Hounsfeild Tensometer Torsion Tensile Tester Vickers Hardness Tester. Summery introduction This project will go into depth of the usage of material selection. After being paired with a fellow student we were given the task of testing 0.1% Carbon Steel‚ 0.4% heat treated steel along with a unknown specimen. To test these materials I will be using 4 types of methods Visual Inspection Hounsfeild Tensometer Torsion Tensile Tester Vickers Hardness Tester. Visual test While

Composite materials A composite material consists of two or more physically and/or chemically distinct‚ suitably arranged or distributed phases‚ with an interface separating them. It has characteristics that are not depicted by any of the components in isolation Most commonly‚ composite materials have a bulk phase‚ which is continuous‚ called the matrix‚ and one dispersed‚ non-continuous‚ phase called the reinforcement‚ which is usually harder and stronger. The arrangement of the fiber in the matrix

STRENGTH OF MATERIAL TENSILE TESTING OF METALS STRENGTH OF MATERIAL TENSILE TESTING OF METALS OBJECTIVE : Tension test is carried out; to obtain the stress-strain diagram‚ to determine the tensile properties and hence to get valuable information about the mechanical behavior and the engineering performance of the material… INTRODUCTION: A tensile test‚ also known as a tension test‚ tests a material’s strength. It’s a mechanical

Composite Materials A composite is a combination of two or more materials bonded together to gain some overall necessary goods. Types of composite include: laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two

[pic] INTRODUCTION Materials are an important determinant of the total cost of production‚ as it constitutes around 50% to 60% of total cost. Materials as our input in production system are receiving attention of the industrialists from 1900 onwards. Since the beginning of 20th century‚ materials have been occupying a place of importance among the M’s of Materials‚ Money‚ Man‚ Machine and this will continue to be so in the years to come. Materials management is one of the areas covered
