Sieter Hall Building Lab Report

5. In HANESS, the men age 18 and over had an average height of 69 inches and an SD of 3 inches. The histograms is show below, with a normal curve. The percentage of men with heights between 66 inches and 72 inches is exactly equal to the area between (a) and (b) under (c). This percentage is approximately equal to the area between (d) and (e) under the (f). Fill in the blanks.

2. Determine the room’s air temperature, and also measure the diameter of the glass tube. Record the data.

Think about what you need to measure before you measure. i.e., I want to measure to see how long Charles’ body is

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

If they do not, but are within the acceptable margin of error of ±20√4=±40’’, each angle is corrected to create a sum of 360˚. For this project, the angles added to 360˚ 00’ 10’’. After each angle is corrected, angle 412 is 78˚31’03’’, angle 123 is 99˚01’23’’, angle 234 is 92˚32’21’’, and angle 341 is 89˚53’13’’. After using the Total Station, the Auto level is used to measure the elevations of each point. The known elevation outside of Powell is 380’. The Auto level is placed between each point to measure the backsight and foresight. Once all the points are measured, all the backsights and foresights can be measured with the difference taken to find the error. With this project, the error was -0.128’. Next, the pacing between each point must be taken to find the correction for each elevation with the equation, (distance from known elevation/total level network distance) X total error. The total pacing for the project is 235 steps with a pace of 2.31 feet per step. After the corrections, point 4 is 379.384’, point 3 is 378.182’, point 2 is 379.093’, and point 1 is 379.645’. A transit is used to find the true north from the magnetic

Make three exposures using given technical factors on a phantom knee in PA position . Include saline bags in exposures 1 and 2 to demonstrate patient soft tissue thickness.

Using a measuring tape on the wall each member of the lab group separately stood with either side against the tape and extended the arm beside the wall as high as possible. This height was recorded in centimeters. Next each lab member separately applied chalk to their fingertips, crouched down beside the tape on the wall, and jumped as high as they could while hitting the measuring tape at their highest point. This measurement was again recorded in centimeters. Then the height the lab member’s arm extended while standing was subtracted from the height when they jumped. This number denoted the vertical height jumped. For the jump height measurements a scatter plot was constructed. In order to do this, the data was again entered into excel, highlighted, insert chart and the first scatter plot choice was chosen. It was then that it was necessary to edit our axes and other parts of the graph. The x-axis was right-clicked and format axis was selected and fixed was selected and 20.0 was entered into the blank. Following this, a trend line was added to the graph by right clicking on a data point. A drop down popped up, and from there add trend line was selected from the choices.

To answer this problem, first I needed to gather important information about what they told me in the document. The information I got was the height of the MCLC library balcony which was 417 inches and and the x and y data table which x represents the number of rubber bands they used and y the jumping distance the barbie reached for each of the rubber bands they used. My plan was to make a graph to find the slope of the line. Then with the slope, I needed to make an equation that best its the table and graph.

To indicate whether a surface is level or plumb spirit level or Bubble level is used. Original spirit levels are comprised of two bananas shaped curved glass vials at each point of view. They are little complicated in structure. The spirit level will be placed in such a way that the tripod in between two points and the height difference between those points can be calculated easily. To mark the points markers in rock or soil are used. A leveling rod equipped with measured graduations is placed on each point. The focus of the viewer will be pointed on each road and values can be calculated from it. Calculate the difference of back and forward value to find the height difference.

To become familiar with the scientific method and know how to use the metric system of measurement. A person who has long upper limbs tends to be tall and vice versa. The length of a person’s arm in centimeter is equal to 40% of his or her height in centimeter. Materials needed for this experiment are the calculator, metric stick or measuring tape, and 5 students. The formula to calculate the expected arm length is the height in centimeter times 0.4.

Locate the stairs that will be used in this experiment. Create a line or marker for the front edge spot for the slinky, at the highest point of the stairs. Grab the medium slinky and place the front edge on that marker. Now, push the slinky down the steps and record the time it takes to reach the bottom. Due this three times to create a range.

Whereas using trigonometry, the measurements can only be assumed, so the accuracy is very limited. Another limitation was that the home made pepper clinometer was not calibrated, meaning the weighted string was not at zero when the clinometer was parallel with the ground. Therefore, the measurements may be inaccurate due to a possible systematic error. If the clinometer was not calibrated, the measured angle of elevation would be a few degrees off, which would then alter the

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.

You will be given both a short ruler and a Vernier caliper to measure your small items. Remember, scientists always estimate between the smallest divisions on their measuring devices. In your lab notebook, record the dimensions (with units!) in the second and third columns in your data table. Think about how many dimensions are needed to accurately describe each object. You may have different numbers of measurements for each entry in your table. Make sure to leave enough room to fit all of your measurements when drawing your table!

At the four feet measurement, the angle was easier to see therefor the height was a little easier to calculate versus the ground measurement. Although these numbers were in the general area, for all three calculations some error was present due to estimations of the angle as well as holding the protractor. This was difficult because it needed to be in the exact same spot for all calculations since a group member needed to hold it, the proctor did move slightly throwing off the numbers only a few degrees. The difficulties in this project was obtaining the data from the ground because it was difficult to get underneath the protractor to see the angle; someone was on the ground looking up at the building leaving room for interpretation of the angle measure. This process could have been done differently by choosing a spot with a lower vantage point. For example, if a group was to measure this building again and there were stairs, to stand at the bottom of the stairs while still on the ground level that the building is on. This way that the calculations are still measuring from the ground to the top of the building, but it would be a lot easier to see underneath the angle versus lying on the
