A. Relationship between friction and normal force (horizontal surface). Prelab problem: In this experiment, you will apply a horizontal force to a box loaded with weights, in order to Use your results from b) and c) to calculate the n av T Maimaitiyili · 2010 — However, it will be quite helpful if we able to do some more experiments. Acknowledgment. We are grateful to FRM II for gave us a chance to make our experiment. Research output: Chapter in Book/Report/Conference proceeding › Paper in conference proceeding An alternative is to use the motor torques, though friction causes large disturbances. The Coulomb friction can be quite well known when a joint is moving, but has much larger uncertainties for LU Robotics Laboratory.

There are two types of friction: kinetic and static. Kinetic friction is the friction between surfaces in relative motion. In this experiment, the frictional force be we n a oodeblock nd he surf aceof hor izont lnd nc nedpl wilbem esurd, nd from the plotd data, the coefficients of static and kinetic friction will be obtained. The angle of repose method will also be used to determine the coefficient of static friction. Lastly, the coefficient of kinetic Experiment 5: Friction.

The sensor measures the amount of force that is parallel to the hook axis. Lab setup for Static and Kinetic Friction using Vernier Force Sensor. 2016-12-31 In our experiment we will first determine the coefficients of static and kinetic friction between two wood surfaces (a wood block and a wood plank).

Lab Report: Pipe Friction MODULE LEADER: Dr. MEHDI NAZARINIA 1. Introduction The flow of fluid in a pipe under pressure is used to reach many goals. A good knowledge of the fluid flow and pipe pressure at some point along the path of the pipe may facilitate to determine the size, capacity and material of the pipe for a system.

OBJECTIVES. • Use a Force Sensor to measure the force of   In the following section, results closest to the system runner/ice will be reviewed. We concentrate on a temperature range between −2°C and  Design and conduct experiments in order to explore the questions below. In each case, briefly describe your experiment and the results. • Is the equality preserved   In this lab, we will be examining kinetic friction, which is the friction between an which is obviously slowing down throughout the experiment and trials when However, there may be some errors in our final results due to a few com It is the objective of this experiment to enable pressure loss measurements to be where f is a dimensionless constant (i.e. friction factor) which is a function of.

See the section on How to Prepare Your Lab Reports for an example. Your lab reports should be a concise but complete summary of your experiment and its results The coefficient of friction is a ratio of two forces: a force perpendi Nov 6, 2013 Title Name/ DatePurpose -- the purpose of this lab is to determine the coefficient of kinetic and static friction betw ______ and μk to be _____.

3. You should be able to design and perform an experiment to determine the coefficient of friction Please self-assess your lab report using the ru 23 Apr 2014 In this experiment, we will study the forces of friction when an the results and determine the relative effectiveness of these methods. Essential pre-lab reading: “Physics for Engineers and Scientists : Extended 3rd Ed direction of motion, in which direction does the kinetic frictional force act? Take time to answer the 'What Do You Think?' question(s) in the Lab Report section. In this experiment we will measure the effects of friction on the motion of a If this experiment is being submitted as a lab report, derive the relation : = tan 2. BY F. P. BOWDEN, F.R.S., Laboratory of Physical Chemistry, give similar results and show that even at moderate speeds the local surface temperature The experiments are also interesting in that they show that the real area of cont 3. Statistical Analysis for Study II. 4.

Friction occurs because an object interacts with either the surface it lays upon, the medium it is contained in, or both. Only in a complete vacuum can a system be free of friction. Static friction 2016-11-02 · Experiment 4 friction factor 1.
