Simple Distillation Experimental Organic Chemistry: A Miniscale and Microscale Approach. 4th Edition. By Gilbert and Martin. Section: 4.4 Introduction: Distillation is a technique used to purify various liquids. In a simple distillation‚ a liquid is boiled and the vapors work through the apparatus until they reach the condenser where they are cooled and reliquified. Liquids are separated based upon their differences in boiling point in which each pure substance is at least greater than 40-50

Simple Pendulum Experiment In this experiment you will make a simple pendulum consisting of a plumb bob and a piece of string anchored at two points. By attaching the string to two points the normal precession that would occur will be eliminated.

I. Abstract: This experiment tests two parameters‚ deflection and strain‚ associated with a simple truss subjected to a loading at its bottom end as would be the case if a constructed bridge was subjected to loadings by cars‚ trucks‚ trailers‚ pedestrians‚ etc. The set up contained an instrumented truss mounted in a test frame with strain gauges attached to the center of each truss member and a linear potentiometer displacement transducer (LPDT) placed underneath the truss assembly to measure displacement

Simple Pendulum PURPOSE The purpose of this experiment is to study how the period of a pendulum depends on length‚ mass‚ and amplitude of the swing. THEORY A simple pendulum is an idealized model consisting of a point mass (sometimes called a pendulum bob) suspended by a massless unstretchable string. When the bob is pulled to one side of its straight down equilibrium position and released‚ it oscillates about the equilibrium position. The path of the bob is not a straight line but an arc
