Linear Variable Displacement Transducer (LVDT): A very basic transducer which is always useful in the field of instrumentation‚ I have studied about this in my college days. Now let me explain about the LVDT with its Principle of Operation and I will explain how it is constructed for its well known operation and you can understand the working of LVDT. Principle of LVDT: LVDT works under the principle of mutual induction‚ and the displacement which is a non-electrical energy is converted into an

Theory In order to gain understanding on the workings of these phenomena‚ I will be starting with the mathematical expressions for both a single pendulum and the coupled pendulum system‚ in particular the equation of motion: Where J is the moment of inertia (=)‚ is the length of the pendula‚ and is the length down the pendulum of the coupling device. If we then use the identity‚ and assume that‚ for small angles‚ we can simplify this equation to: As the coupled pendula system exhibit two modes‚ this

Three main causes were identified: the lack of credibility or time inconsistency theory‚ inflation inertia and the wealth effects. a. Lack of Credibility According to (Calvo 1986)‚ who first put forth the lack of credibility theory as an explanation to ERBS failures‚ economic agents expect that the government is going to abandon the peg at some point

Explain how it could have been made better so that the car could have performed better. During its test‚ my mousetrap car curved to the right causing it to crash into a wall and stop short of its full potential. However‚ the car still traveled the the entirety of the 11 meters required for the maximum number of points. The reasons that my mousetrap
