... the vertical shaft. The linear kinetic energy from the falling masses on the hanger was converted to rotational energy of the horizontal crossbar. The moment of Inertia of this system should theoretically be I=2MR2 where M is equal to the weight added to one side of the crossbar, I is equal to the inertia, and R is the distance between the vertical shaft and the masses. The ... were taken, the masses were removed, and measurements were taken without the masses. This was done so that the inertia of the system could be subtracted from the inertia of the system with the masses. The differe...

... is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. As the potato is a plant cell, it contains a vacuole and a ... as fair as possible), and I will then weigh them and record the results. These will then be put into tables and will be used in graphs. I will also measure the temperature in the room. I am going to do the experiment three times, in each solution, and I will ... the equipment I am going to...

... is increased and as the concentration becomes higher the loss in mass becomes greater because they are not accurate enough to prove this true. The two different graphs (one of change in mass and the other of percentage change) both give very similar best-fit lines. The only difference is that one results shows raw data and the other processed results, so it ... and recorded the weights. 7. I swiftly put 3 potato chips into each beaker and then started my stopwatch. 3 chips were used to create an average which gave me a better set of results and more accurate graphs. 8. Whilst waiting I ...

... and so confirms that pressure increases uniformly with volume. The graphs do not pass through 0 Celcius, instead (if the line is retracted back), they intercept x (temperature) at -273 C. This is known as absolute zero, and is known as 0°C on the Kelvin temperature scale. Charles' Law The volume of a fixed mass of gas is directly proportional to its absolute temperature if the pressure ... five other points were noted between these two temperatures. This should provide is with enough information to use graphs and will make any anomalous results easier to see, as they will be out of the...

... bridge. 3. General Approach: I approached this problem as any great engineer would, by first drawing a free body diagram. I did this for both parts of the problem. In the first part, I neglected member weight and in the second part, considered only member weight. I also labeled all external and ... this, I came up with my general equations for both parts of the problem. I then used Quattro Pro to analyze my data and created graphs of my data (see appendices C and D). 4. Results: Part 1: For part one, I solved for the member forces in terms of a simulated load (P) on the bridge (appendix ...
