These approaches can be used to understand the non-linearity and further to control a dynamic system efficiently by using the Kinetic and Potential Energy of the system. Here, we choose an inverted Double Pendulum System as the mechanical system for our analysis.
A_a = Cross sectional area of flux path [m2]. μ_0 = Permeability of air. Fig-1.3(differential drive mode to get force) This is the differential driving mode of AMB model which contains the two E- actuator facing opposite to each other. Two power amplifier is used to supply current to actuator. The force-current coefficient ki is the actuator
By whatever amount the net force acting on the cart changes, I believe its acceleration will change proportionally. Because the relationship is linear, the results on the graph will be linear. This can be shown mathematically as: a ∝ F, or in words “a is proportional to F”. Therefore, a=kF, which can be rearranged to get F=(1/k)a. We know that F=ma where the mass is the cart plus the weights with friction considered, and we know that weight=mass x gravitational field strength.
INTRODUCTION Transdermal delivery technology overcomes the disadvantages associated with oral administered drugs such as poor drug absorption or enzymatic degradation in the gastrointestinal. The needle small size causes minimal trauma at the penetration site, painless drug delivery, and precise control of volume of drug delivery. Micro-Electro-Mechanical-Systems (MEMS) is a rare micro fabrication technology which is proposed for the improvement of transdermal delivery. After several years of research, many mechanical systems are now feasible on a micro scale. Devices like micro pumps, micro needles, miniature mixers, etc.
CHAPTER 2 LITERATURE REVIEW This chapter presents literatures survey on past research work on mechanical micromachining, pure laser machining at macro, meso and micro scale, Laser assisted machining at macro, meso and micro scale, micro cutting tools and tool coatings. 2.1 MECHANICAL MICROMACHINING The trend of micro-miniaturization (meso 100µm-10µm and micro 0.1-100µm) of the products and its parts has already become forceful in industry, especially in field of biomedical, electro optics, automotive, aerospace and information technology. Specific applications include micro scale fuel cells, fluidic micro chemical reactors requiring micro scale pumps, valves and mixing devices, micro fluidic systems, micro holes for fiber optics, micro nozzles
Switch the motor which will stops at 180 intervals, to note down corresponding angle and torque value. Curve may be plotted, drawn between angle of twist and torque for further analysis. The fig 3.5 shows the typical torque v/s angle of twist of one specimen sample at two gauge lengths and that of corresponding stitched samples. Curves show typical behavior and also are indicating the differences when the gauge length is changed and sample

It enabled structuring of materials which manipulate EM wave beams exhibit some properties surprisingly in manners previously unimaginable namely backward propagation, dopler effect, reverse vavilov-Cerenkov effect , negative refraction [4,5], cloaking . All these properties depends on the structurization of the metameterial molecules rather than composition . Theoretically these materials are proposed by pendry et al.. And demonstrated experimentally by smith et al.. Metamaterials have gained the attraction by various research teams in recent years because of wide application in Microwave, Terahertz, optical frequencies
