An axle friction lab report is a document that presents the results of a laboratory experiment that aims to measure the frictional forces acting on an axle. The purpose of this experiment is to understand the behavior of friction in a real-world situation, as well as to determine the factors that influence the amount of friction present.

To conduct the experiment, a set-up is required that includes an axle, a load, and a means of measuring the frictional forces. The axle is typically made of metal and is supported by bearings, which allow it to rotate freely. The load is applied to the axle by attaching weights or other objects to the end of the axle. The frictional forces acting on the axle can be measured using a variety of methods, such as a spring scale or a load cell.

In the experiment, the load is gradually increased and the frictional forces acting on the axle are measured at each increment. This allows the relationship between the load and the friction to be determined. The results of the experiment can then be plotted on a graph to visualize this relationship.

There are several factors that can influence the amount of friction present in an axle. These include the material of the axle, the surface roughness of the axle, and the type of lubrication used. In the lab report, these factors should be discussed and their impact on the results of the experiment should be analyzed.

In addition to presenting the results of the experiment, a good lab report should also include a discussion section. In this section, the results of the experiment should be interpreted and compared to theoretical predictions. Any discrepancies between the results and the predictions should be explained, and the limitations of the experiment should be acknowledged.

Overall, an axle friction lab report is a valuable tool for understanding the behavior of friction and the factors that influence it. By conducting this experiment and presenting the results in a clear and concise manner, students can gain a deeper understanding of this important physical concept.

Unlike most coefficients in Physics, friction behaves differently depending on whether the object is at rest or at motion. Any report does not have all the above sections will be rejected and returned, and it will be considered as non-submission. For both flat and V-shape belts as the contact angle increases the tensions of belt increases. There is a positive linear relationship between the Reynolds Number and the head loss coefficient. Attendance to lab session is compulsory. Plot a graph versus t2 plot t2 on the abscissa, i. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact.

Static friction Fs occurs when two surfaces are still at rest with respect to each other, but an attempt is being made to cause one of them to slide over the other one. The slope of this linear relationship showed that as the flow rate increases, the velocity increases which means the Reynolds Number gets bigger and the head loss coefficient increases. Hook the string to the spring scale. The peak force seen at the beginning is the maximum static friction and the force after that the kinetic friction. Friction exists between two surfaces which are in contact with each other, even if they appear to be smooth. Set 2- Static and sliding forces as a function of the force of gravity, Refer to Fig. Experiment: Using the measured distances 100mm to 500mm, intervals of 100mm travelled by the wheel and the expressions i.

The physic's definition of energy efficiency is very similar. Weir has many advantages such as capability of precisely measuring a wide range of flows, easy to construct, tends to provide more accurate rating compared to flumes and orifices, can be portable or adjustable, most floating debris tend to pass over the structure. Retrieved from my-cardictionary: my- cardictionary. So, they require a proper clean environment to avoid dust or dirt. Attendance to lab session is compulsory.

The small block is placed on the workbench surface with the plastic rubber side down. My average was 5. . Download Complete Friction lab report and more Physics Lab Reports in PDF only on Docsity! In any system where a belt is wrapped around a pulley, there is potential for friction between the belt and the belt it is in contact with. The main goal of this laboratory is to determine the coefficient of friction. The experiment used 2 different belt which are flat belt and V-shape belt in order to investigate the relationship and determine the coefficient of friction for both types of belt. Explain the discrepancies between calculated values and experimental data.

Slightly modified procedures were applied in determining the coefficient of kinetic friction µk , where, instead of allowing the block to move from rest it was slightly tapped to allow the block to overcome the force of static friction. Now the source of this energy is the loss in potential energy as the wheel moves down the slope. . Conclusion: Using Newtons second law the coefficient of static friction µst and the coefficient of kinetic friction µk , were more accurately determined. As seen in the standard values both µst and µk were not expected to produce the same value as kinetic friction is slightly lower than static friction. The table below is from Table IV: Coefficients of Static and Sliding Friction Materials Static Sliding Dry Greasy Dry Greasy Hard steel on hard steel 0. It is a non-conservative force; the force used to overcome the frictional force and allow an object to move is dissipated into heat energy and will not return to the system once the movement stops.

Graph of sliding friction force and rolling friction force are plotted as a function of the force of gravity. In theory, coefficient of kinetic friction is a constant, and it should not change if the normal force in this case it is equal to the weight on the object changes. If it is reasonable to assume that friction effects are insignificant then no energy is lost. The wooden block has a layer of plastic hence the experiment was conducted on both the wooden and the plastic side separately to compare the results. Identify the sources of error and explain with calculations or theory involved.

Coefficient of Friction

The coefficient of friction, symbolized by the Greek letter mu µ , is the tool used to measure friction, given by the ratio between the friction and the normal force. On the other hand, ball bearings have very low friction and perform really good but their installation and manufacturing requires high standards of technology and they have far less tolerance. All equations used in the calculations must be shown. There are two different kinds of friction, static and kinetic. There is a necessary discussion of errors due to relevant issues.

Calculated and experimental values must be shown and %errors between them derived. With the many circuits of flow to chose from the student can combine different variations of each to see how the flow responds. Friction Losses Abstract—The purpose of the experiment is to study the differences of roughness, valves and geometries of pipe and how they influence friction losses. References — Books or publications to support theory and discussion. Nursing theories are important to the lives of nurses because they help develop and understand further the nursing practice. This is theoretically incorrect as coefficient of friction cannot have a negative value.
