Bridge Instruments Bridge Instruments Various types of bridge circuits are used in instrumentation. They can operate in either deflection mode or null principle. They give very high degree of accuracy. Bridges Instruments are used to measure • Resistance‚ Inductance‚ Capacitance • Purity of components • Impedances and admittances • Physical parameters Bridge Instruments Types of Bridges • • AC Bridge DC Bridge DC Current Bridge Instruments • Wheatstone bridge and

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

Laboratory Experiment No. 1: Common Laboratory Procedures Objective In this experiment‚ the objectives were to use a balance and measure the volume of the liquids. Theory In the experiment‚ three calculations were used. These are the density‚ relative error and the standard deviation. Density is refers to the mass (m) per unit volume (V) of a material and is often represented by the symbols d or ρ‚ where d = m/V. The density of an object changes with pressure and temperature. Second‚

intermediate and long period perturbations up to the third order. The osculating orbital elements which describe the orbital motion of Nereid are evaluated analytically. The comparison with the numerical integration of the equations of motion gives an accuracy on the level of 0.2 km in the semimajor axis‚ 10-7 in the eccentricity and 10-4 degree in the angular variables over a period of several hundred

determine factual data and the relationship between cause and effects. An example is making in-depth research about the relationship smoking-cancer and answer the question: “Does smoking increase the risk for cancer?” I will always ask myself about the accuracy and completeness. Ones a fact and opinion have been differentiated and the author is not biased‚ and the cause-effect relationship is examined then I need to question the questions. I want to mention that as a critical thinker I need to be cautious

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

History At the end of the 19th Century ‚in the light of recovering French economy after the Franco-Prussian War‚ French republic announced the opening of a competition to design a 1000-foot tall tower for the 1889 Universal Exposition. The location of the tower was determined to be at Champ de Mars in Paris. Gustave Eiffel’s company engineer‚ Maurice and Emile alongside the architect Stephen Souvestre came out with a proposal to enter the competition. Their blueprint was selected unanimously out

Skinput The Human Arm Touch screen Abstract Devices with significant computational power and capabilities can now be easily carried on our bodies. However‚ their small size typically leads to limited interaction space (e.g.‚ diminutive screens‚ buttons‚ and jog wheels) and consequently diminishes their usability and functionality. Since we cannot simply make buttons and screens larger without losing the primary benefit of small size‚ we consider alternative approaches that enhance interactions
