Instrumentation & Measurement: Calibration of Straightness and Flatness Laboratory Report

At the nearby valley wall, there is a distribution of rock lithology including mostly Limestone. The roundness of the samples is all angular, with a mean size of 8.325 cm in diameter. However, the stream bank has more clastic rock samples which have a rounder shape and a smaller mean size of 7.975 cm. These contrasting sections are between alluvium and colluvium data where the alluvium

4) This line is much like a line on a geologic topo map. Explain the similarity.

Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different

Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what is being measured. Precision is the variability in the results from the repeated measurements, and how close the repeated measurements were to one another. In this lab, the method for measuring the volume of the polystyrene spheres is done with the previously stated tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The standard deviation for the entire classes volumes and masses are recorded to determine the densities.

The Granite rock is an intrusive rock that formed from magma coming from beneath the earth’s surface. It went through a slow cooling process that allowed the minerals; mainly quartz and feldspar to form where the result is the coarse texture. The granite went through hydrothermal metamorphism (involves hot fluid) and contact metamorphism. The gneiss, however, being able to withstand high temperatures came from a large country rock. This piece of gneiss broke off from the country rock and got trapped in between as the granite cooled. The gneiss then became the xenolith. This shows that the granite is the younger rock and the gneiss the older. The striations on the Gneiss were caused by faults. A slick-en- side fault caused the horizontal striations

Slope determination is a valid way to calculate density because the slope of the data and the actual slope were close in value. When looking at the slope of the graph with the points, they were all relatively close. Three of the five point were even on the slope line. The formula of (y2-y1/x2-x1) allowed the finding of the slope of the line graphed and it also allowed the comparison to the actual slope of silver. This allowed the calculation of the percent error and also to see how effective slope determination really is. The slope of silver was 10.5g/cm³ and the slope of my findings was 10.15g/cm³. The percent error was low at 3.3% which points to slope determination

We were given an experiment where we had to pick a time range and a few different flavor of gum; sugar and sugar free gum. We had three flavors of gum we completed our experiment with, we had Chiclets, Five spearmint rain, and Trident Layers cherry lime. We chewed each gum for five minutes, two and a half minutes and one minute. The chewing of the gum helped us determine the percentage of sugar that was presented in the different pieces of gum we chewed. The purpose of this lab in to see if we could determine the percentage composition of sugar presented in our gum. Finding sugar in some items are difficult compared to others. Finding the sugar in multiple pieces of gum is pretty easy to do, all you need to do is find an equation the will

Introduction and Method Thousands of years ago, humans wanted to measure height of tall objects, but using a long tape of ruler would be too time consuming and too difficult. However, the Greeks invented a branch of mathematics, which uncovers the relationship between sides and angles within triangles. Today, it is known as trigonometry, and it very useful in science, engineering, astronomy and many other professions. For example, it is impossible to use a tape ruler to measure the distance between Earth and nearby stars, so thee most efficient way to do so is by using trigonometry.

The table shows me that Image E gives a very accurate value, correct to the nearest thirty seconds and meaning my precision in calculating angles has achieved an average (mean) between 0.1 and 0.2 degrees from the true value. The range (difference between small and largest values) is also less that 5% of the average result, suggesting that my angle calculations with different star trails produced repeatable results.

LC = How much an object weighs, HM = the horizontal distance of a person’s hands to what would be the midpoint of their ankles, VM = is the distance between your hands to the floor when your hands are vertical, DM = is the vertical distance between where the lift starts to the final placement of the lift, AM = Angle of asymmetry, FM = Average rate of lifts done per minute and CM = is a

Stone length shall henceforth refer to the length of the stone parallel to the overall direction of the water flow. Stone length was determined using two measurements of length which shared the same starting point: The upstream beginning of the artificial bed. The first was measured to the upstream end of the stone while the second was measured to the downstream end of the stone. Stone length was obtained by subtracting the first measurement from the second measurement. Stone protrusion shall refer to a measurement taken perpendicular to the flow and approximately parallel to gravity. Stone protrusion was determined using two measurements of depth: The first was the depth of the water above the artificial bed. The second was the depth of the water above the stone. Stone protrusion was obtained by subtracting the second depth measurement from the first depth measurement. Stone width shall refer to the measurement taken perpendicular to the both flow and gravity. Stone width was determined by directly measuring the stone along the widest possible perpendicular axis to both gravity and the direction of water flow.
