truss becomes internally statically indeterminate. In this case the truss is termed statically overdeterminate. The SE 110.22 experimental set-up permits investigation and comparison of statically determinate and statically indeterminate trusses. Using the bars and node discs‚ a statically determinate‚ single plane truss is first constructed. On installation of a surplus bar the truss becomes overdeterminate. By way of a load application device‚ straight or inclined forces are applied to the truss

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

Figure 1 below. ! Figure 1 - Set Up of Michelson Interferometer! ! When two light sources have the same wavelength and frequency‚ they are said to be coherent with one another. If they were to be combined at a certain point‚ they are said to be superimposed at that point. When superimposed‚ the two (or more) light waves’ properties can interact and interfere with one another which can lead to two scenarios; the superimposed light waves can reinforce each other to produce a brighter image

I.A Appendix II.A Appendix II.B Summary There are two parts in this experiment where we shall observe the mechanics of fluid flow in a closed conduit and also to find out the characteristics of a centrifugal pump. In the first part‚ we applied the principle of pressure difference across fittings in a closed conduit to find out the loss coefficients of these fittings. Thereafter‚ we determine the individual flow rates of the 3 different lines in the system. With this knowledge‚ sufficient

Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic behavior‚ we can find aggressive behavior‚ where the animal goes towards the stimuli with intentions of attacking‚ or submission

unknowns is important in chemistry because it allows chemists to identify what chemicals they are working with if they have been improperly labeled or if they are trying to determine substances in a compound. Molecular weight and pKa are two properties that help to identify unknown compounds. To find the pKa of an unknown‚ pH meters are used during titrations to measure the potential difference in a solution by measure the difference of hydrogen-ion activity in a solution and reporting the pH. The pH

The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment‚ such as "operating a grinder‚" "using a pressurized water extinguisher‚" or "changing a flat tire." JHAs are not suitable for jobs defined too broadly‚ for example‚ "overhauling an engine"; or too narrowly‚ for example‚ "positioning car jack." What are the benefits of doing a Job Hazard

concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules
