TENSILE STRENGTH TEST
In such a test the specimen, prepared according to TS 138 standards, is subjected to a gradually increasing uniaxial load until fracture occurs. The following properties of the material are usually determined by this test.

FATIGUE STRENGTH TEST
Fatigue performance test is used to determine the strength of materials under the action of fatigue loads, specimens are subjected to repeated or varying forces of specified magnitudes while the cycles or stress reversals are counted to destruction. Fatigue test machine subjects the specimen to pure bending by means of weights. To establish the fatigue strength of a material, quite a number of tests are necessary because of the statistical nature of fatigue. For the rotating-beam test a constant bending load is applied, and the number of revolutions of the beam required for failure is recorded.

CHARPY-IZOD IMPACT TEST 
The impact test is designed to have a sound insight into the mechanical properties of metals under the conditions conductive to brittle fracture. In the impact test, the energy required for the rupture of the sample under dynamic loading is to be determined. A notched material, which displays ductile behaviour in a simple tension test, may behave like a brittle material under impact loading.

HARDNESS TEST
Hardness measurements are widely used in laboratory and as industrial tests in order to characterise the mechanical property that is related to the wear resistance of a material its resistance to permanent or plastic deformation. In this test following harness measurement methods are used:

MICROPROCESSOR APPLICATIONS AND PROGRAMMING IN MECHANICAL ENGINEERING
Microprocessor   is a semiconductor device consisting of electronic logic circuits manufactured by using either large scale or a very large-scale integration technique. The  microprocessor  is capable  of performing  computing  functions  and  making  decisions to change the sequence  of  program execution. Few experiments which is to be performed using  8085 microprocessor set take place in one session.  The overall objective is to teach the meaning of the microprocessor and application areas; programming  methods, their abilities and significance in the control of various equipment, step and direct current (DC) motors, relays, solenoids, switches  etc. So basic control methodology using microprocessor may be gained and applied in real life problems in mechanical engineering.  

MEASUREMENT OF CUTTING FORCES
In this experiment, oblique cutting method is used to measure the forces acting on a cutting tool under working conditions using a tool force dynamometer. Forces, which act on the tool, Fr (radial), Ft (tangential), Fa (axial), are directly read from the force dynamometer. A series of experiments is performed to determine the effect of variation in depth of cut (DOC), rate of feed (ROF), and cutting speed (CS).

SLIPPING FRICTION
The study of friction has to take into account different circumstances, namely the static and slipping situation. The measurement of coefficients of friction is of great importance in designing  moving mechanical elements since friction is a source of heat and a cause of wear. The experiment is intended to give the ability to determine the coefficient of sliding friction between the mild steel wheels and a bar of various materials, to verify the equation of motion for the oscillating bar, to show that the coefficient of friction is not dependent on the mass of the bar, to investigate the effect of the vertical position of gravity center of the bar.

SCREW THREADS EFFICIENCY
Generally screw threads are used to clamp bolted parts together, but another function is to move one part relative to another. The lead screw of a lathe is an obvious case. A different example is found in a screw jack used for lifting a vehicle when changing a wheel. The experiment is intended give the ability to measure the effort required to raise different loads on each screw and hence to determine the friction and mechanical efficiency of each screw. 

PIVOT BEARING FRICTION
In most cases in the design of a thrust bearing axial load in the shaft must be carried on a large enough area to be safe, and the shaft must be located in position as it revolves. Friction in a thrust bearing is usually a disadvantage as it causes a loss of energy in the machine. The experiment is intended to give the ability to study the effect of the conical angle of a pivot bearing and to obtain the coefficients of friction for bearings of different design.

UNIGRAPHICS CAD/CAM/CAE PACKAGE
The software allows users to create three-dimensional models of mechanical devices to be used in the design of various products.  Solid Works is now in use in the mechanical engineering department’s computer technology classroom, where students use modern software to conduct simulations or virtual experiments on a variety of engineering systems and processes. Students have found this windows-based CAD software very easy to learn and use.

CADKEY CAD/CAM PACKAGE

The CADKEY product line is used by industrial designers, design and mechanical engineers, moldmakers, manufacturing engineers and technical illustrators in a wide range of industries and applications. Products designed with CADKEY software include aircraft, automobiles, medical products, machines, computer equipment, naval vehicles, satellites, consumer products, furniture, toys, sporting goods, and electronic products.

AutoCAD 2000 CAD PACKAGE

AutoCAD is a general purpose Computer Aided Drawing / Design (CAD/D) package which runs on a wide variety of low cost microcomputers as well as high cost workstations.

AutoCAD is an advanced-comprehensive drawing and design tool, written in ‘C’ programming language. It was first launched in 1982 and has been continuously developed, with regular major updates (from Release 1.0 to Release 13 for Windows and AutoCAD 2002i). Therefore, AutoCAD has kept pace with advancements in CAD/D technology and increased in sophistication without any corresponding increase in relative cost or restriction in availability.

AutoCAD program may also be customized to suit the particular needs of the user. For example, the full AutoCAD package incorporates a high level programming called AutoLISP which enables the user to create automatic drafting routines for specialist shapes and extend the standard AutoCAD drawing facilities as required

WELDING
Welding is a process by which two materials, usually metals, and is permanently joined together by coalescence, which is induced by a combination of temperature, pressure, and metallurgical conditions. The particular combination of these variables can range from high temperature with no pressure to high pressure with no increase in temperature. Thus welding can be accomplished under a wide variety of conditions, and a number of welding processes have been developed. While welding has become a dominant joining processes in manufacturing, the average person has little appreciation of its role or the large number of metal products that would have to be drastically modified, would be considerably more costly, or could not perform as efficiently if it were not available.

CASTING
Casting is a solidification process where the molten material is poured into a mold and then allowed to freeze into the desired final shape. Many of the structural features that ultimately control product properties are set during solidification. Furthermore, many casting defects, such as gas porosity and solidification shrinkage, are solidification phenomena, and they can be reduced or eliminated by controlling the solidification.

ELECTROPLATING
Electroplating or electrodeposition may be defined as the production of metal coatings on solid substrates by the action of an electric current. In contrast to various other processes of applying coatings, electroplated coatings are applied to improve appearance, corrosion resistance, and physico-chemical properties of the surfaces (hardness, electrical and thermal conductivity, solderability, reflectivity etc.)
