Although different in many respects‚ liquids and gases have a common characteristic in which they differ from solids; they are fluids‚ lacking the ability of solids to offer permanent resistance to a deforming force. Fluids flow under the

Chapter one Introducing Mechatronics Objectives The objectives of this chapter are that‚ after studying it‚ the reader should be able to: Explain what is meant by mechatronics and appreciate its relevance in engineering design. Explain what is meant by a system and define the elements of measurement systems. Describe the various forms and elements of open-loop and closed-loop control systems. Recognise the need for models of systems in order to predict their behaviour. ● ● ● ● 1.1 What is mechatronics

It is well known that ratcheting can reduce fatigue life or cause failure of piping components or pressure vessel systems subjected to seismic or other cyclic loads. For design and analysis of these types of structures

PERTH COLLEGE UHI 12 INSTRUMENTATION OF A WIND TUNNEL PROJECT BEng(Hons) Gaurab Ghosal ABSTRACT The wind tunnel being built in Scone airport is a closed loop wind tunnel. On completion this will provide a much needed facility for education purpose as it can be used by engineering students for aerodynamic evaluations. To conduct these evaluation proper evaluating tools needs to be setup. In this section the possible instruments that can be setup in this wind tunnel has been evaluated with

is made between the measured deflection values and theoretical deflection values. Among reasons for discrepancies are likely the parallax errors when reading was being taken from the dial gauge due to the sensitivity of the dial gauge. A slight vibration or impact on the table will affect the reading on dial gauge. Generally‚ theoretical values exceed experimental values. Introduction: The proving of Deflection of Circular shape is based on the diameter deflection elastically under load. Applied

capable of embedding fiber sensors into parts made of metal alloys with high melting temperatures. Fiber Bragg Grating (FBG) sensors were selected as the most promising sensor candidate. The embedded FBG sensors were characterized for temperature and strain measurements. The embedded FBG sensors in nickel and stainless steel provided high sensitivity‚ good accuracy‚ and

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing

mechanical properties of the material and has direct implications on the design and construction of the end product. This test is usually done prior to any decision being made on the materials use. The theory behind tensile testing is to measure the stress-strain response of the material. By doing so you obtain the yield strength and ultimate tensile strength as some of the results and also provides information on how brittle/ductile the material is‚ which is vital in the future usage of the material in testing

Abstract A tensile test was conducted on an Instron tensile machine using a 3/16 inch copper rod. Using data acquired stress and strain was calculated and plotted on Excel to analyze stress strain curve. Modulus of elasticity‚ 0.2% yield stress‚ ultimate tensile stress and % elongation were also calculated. Introduction A tension test is probably the most fundamental type of mechanical test you can perform on material. Tensile tests are simple‚ relatively inexpensive‚ and fully standardized
