The Effects of Experimental and Theoretical Horizontal Forces - Lab Report Example

The report indicates three different purposes as far as understanding the behavior of horizontal forces matter. For the First experiment, a load of 500 grams moved nine times along the bent arch. The reason for doing so was to check on the effect of moving the same point load over a series of distances. The resultant was a corresponding series of different moment and shear diagrams. The second and first experiments were similar save for the fact that the former had fixed supports. The result of having these supports meant that the moments generated were slightly smaller than the corresponding ones in the first experiment. The third focused on the effects of several loads on two types of cantilever trusses.

The first part of the test had a cantilever truss that was structurally determinate. In this truss, the rod diameter used was 6mm and the Material strength was 210Gpa. The meaning of such an output was that the forces corresponded with the strains for the same loading. The first part considered understanding the statically determinate truss in the presence of a horizontal force. However, the second part concentrated on the effect of having a redundant member present in the structurally indeterminate truss.

Redundant members had no use in the structure of the trust. They neither carried the tension of compression forces. The forces underwent neutralization in order to cancel one another out. Therefore, the member is forceless. In the end, the experiment was successful as there were graphs that interpreted the result of the three experiments. Several software helped in the analysis of the work such as SPSS and Excel, which showed the operation of the different parameters present in the whole process.

There are several effects of loading an arch with loads. The result is that there are always deflections. The movement from one point to another occurs at displaceable points. These points are supports that move in nature. The term rolled supports works for such a kind. The experiments are having a pinned and turned support at two ends, and there will always be movement on the side of the rollers. The loads on the arch make it undergo stress and so in overcoming the stress, the result is movement.

The point n consideration is that the more the weights appear on the arch, the more movement is anticipated. 

The rollers are the type of support that allows movement in the horizontal direction. The movement is because of the different components f forces occurring in the arch (Kanovsky, 2012). The point in moving different kinds of loads from one point to another is to help in the understanding of the effect of loads from different views. For example, in 1988, Prof. Dan at the University of Cambridge discovered that there are movement in the structure if an arch provided loads exists. He placed a load of 600 tons on an arc that had one pinned and rolled support at both ends and after some time, the arch started to move away from its original position.

The result showed deflection in the structure. To determine the deflection in the arch, he had to measure the original distances and dimension. These values of the arch helped people understand the real meaning of deflection. Over the years, there has been the situation in which people have had believes that the possibility of determining of loads is okay without necessarily finding them out in nature. The point of finding that a scientist can look at the behavior of the arch to determine loads and displacement is almost a refute to many.

The idea most certainly amount occurred disturbed many people (Kanovsky, 2012). There are the several experiment in the past that look to understand the relationship between the occurrence of loads and the behavior anticipated for the arch or beam present at the time of the experiment. Take into consideration the existence of the several loads that undergo application on the arch (Kanovsky, 2012). The behavior of the weights in comparison to the existing structure helps to understand the correlation between these two kinds of parameters.

Many believe that the more loads one adds to a structure, the more the degree of deflection anticipated. Over the years, different weights have been present on the arch. The movement of the load from one point to another helps to understand the behavior of how the beam or the arch react to such loads placed on them. The result of the behavior of certain beams and arch in the presence of loads can undergo presentation in terms of graphs that clearly explain the way the two parameters behave. The graphs plotted on paper are sometimes linear of having curves in their nature of existence (Higgins, 2014).

Usually, the figures go directly as one load makes it on the arch. The more loads added to the beam or arch, the more likely of the a possibility of breaking. The graphs show that there are two axes, which is to say, the Y, and X axis. The Y axis has the loads on it whereas the X one has the movement to f the arch from one point to another. The beginning step is to have the starting point to another. Each measurement on the pair shows the corresponding one on the ground. Several important tools matter for one to have a successful experiment.

These tools are; 1. Loads, for example, a 500 ton. 2. Arch and Beam mere dummies to represent the arches and beams. 3. Measuring equipment such as a veneer calipers and ruler to mark get the distances made by the moving arch. 4. Stationary to record the observations under which the arch goes when having loads on it. 5. Supports. There has to be support for the arch to be in place. They are of two kinds, that Rollers and Pins. The pins do not move and resist loads in both the horizontal and vertical directions.

The other hinge support resists loads in the horizontal directions alone. They move. The movement of the rollers is the measurement on which one bases to determine that effect of the weight son the arch. The issue at hand is that suppose that there are rollers, and then the arch would undoubtedly collapse as there would be no way to remove the stress of the loads. Structural Analysis The analysis of structure has over the years grown from a simple level to a sophisticated level of calculations.

The past had the mathematical calculation that helped in the determination of forces.
