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.

Q: Do the results support your hypothesis? The physic's definition is very reasonable because the rubber is the main and only source of energy that is applied to the car. All equations used in the calculations must be shown. The results were infact very similar. The purpose of this experiment was to calculate the coefficient of kinetic friction , the coefficient of static friction , and to verify the relationship between , and the weight of an object. Belt friction is a term described as the frictional forces between a belt and a surface. All equations used in the calculations must be shown. Apparatus — a description and diagrams of the apparatus, diagrams must be fully labelled.

The weights of the block increased by adding in turn the weights of 0. By plotting this graph for globe and gate valve, different trend can be observed and frictional losses can be analysed. Therefore the static friction force is zero. The size of the wheel in comparison to the axle it is placed on greatly affects the torque or the pulling force as well as the pulling distance. Unlike most coefficients in Physics, friction behaves differently depending on whether the object is at rest or at motion. The horizontal pulling force measured, which maintains a uniform motion on the rolling rods as the rolling friction force FR.

Golnoush Zamiri Experimental Data. The following shows the procedure for each se of experiment. Marks will be deducted for late submission. Some other experimental errors could have been that the wooden planks were defected or the spring scale was defected. The heavier the block is, the larger the friction.

This is due to the fact that in turbulent flow, a thin viscous layer is formed near the pipe surface which causes a loss in energy, while in laminar flow, this viscous layer is non-existent. Kinetic friction occurs when an object is already in motion. Adding to that different material will make the frictional force vary while the best way to reduce the frictional force to move the block would be the rolling method since insignificant frictional force was observed in this method. Compare the calculated values with the experimental data Discussions: Plot a graph of time t2 vs distance s for calculated and experimental data. The plain bearings are made up of polymer, bronze or ball. Based on contacting each other. 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.

As efficiency of a machine and the cots of the bearings are always inversely proportional, a plain bearing can be easily made and require low cost and technology but it provides a very high friction thus comprising on the power of the machine. We will use four types of different bearings made up nylon, brass and steel plain bearings and one rolling element bearing. 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. Introduction: Friction can be described as the force resisting the relative motion of surfaces sliding against each other. The smallest was rolling friction.

References — Books or publications to support theory and discussion. This lab is very beneficial because friction is one of the most common forces in day to day life. Results — Tabulation of raw readings and the calculated ones. Conclusion — conclude if the aim or objective is achieved. Overview: Friction exists when a physical object attempts to counteract the resistive force encountered while being transitioned into kinetic motion F, or static motion F, at rest. Energy in a rolling wheel Referring to Figure 1 when the wheel is released from rest and subsequently rolls down the slope, it accelerates and hence gains energy.

It is possible for the coefficient of friction to be greater than one, since the friction force is the force opposing the movement of the object and normal is proportional to the weight of the object, therefore it is possible for the friction force to be greater than the normal force which would result in the coefficient of friction being greater than 1. Pull the spring scale slowly, Measure the force needed to keep the book rolling at a constant speed. Calculation of Kinetic coefficient of friction Apparatus: Axle is a solid wheel fixed on an axle. All variables used in the theory section must be identified.

Coefficient of Friction

The smallest amount of force was the rolling friction. Post Lab Questions Q: Which type of friction was the largest? This incorrect value might be caused by mistakes and error during the experiment such as not supporting the weight hanger while putting in the weight causing the momentum of the weight put to exert force on the pulley causing the pulley to start rotating by larger force than the force measured. The main goal of this laboratory is to determine the coefficient of friction. Listing errors without justification is not sufficient and this will not gain any marks. Therefore, you must find a balanced ratio between the size of the wheel and the axle because if it has too little power, it will not end up not moving at all. Conclusion — conclude if the aim or objective is achieved.
