Exporting _______________ gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving. One factor that is used is friction. Friction happens when two surfaces rub against each other and may cause heat. Also there are four types of friction which are static‚ sliding‚ rolling‚ and fluid friction. The company needs the class to find out what type of flooring is best to use to stop a cargo box from moving. They have game systems that are imported and exported

Coefficient of Kinetic Friction Objective: After completing this experiment‚ you should be able to measure the coefficient of sliding friction of an object that is located on an inclined plane. Apparatus: Inclined Plane Pulley attachment for plane Wooden blcok‚ with hook attached Meterstick Felt Set of masses String Protractor Procedure: 1. Place the board in the position shown in Figure 7-1. 2. The angle of the board should be small enough so that the wooden block will not slide

Destiny Stuart Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and

In this investigation three different variables were tested to determine their effect on the force of friction. All throughout the lab it was important to record the data found to identify how much the three variables affected the force of friction. The purpose of the first part of the lab‚ 4.1 What a Drag!‚ was to measure the force required to pull a block over five different surfaces. The sliding surfaces used in the lab were the tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sandpaper

Purpose/Problem/Question Which type of friction is the largest force – static‚ sliding‚ or rolling? Which is the smallest? II. Background Information From our previous activities that we did in class‚ I know that static friction is a very large force. The force is larger than rolling‚ sliding‚ and fluid friction. I also learned that rolling friction is the smallest type of force. This information may connect to my final analysis. III. Hypothesis If static friction is the largest force‚ then either

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. Introduction Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipe. This energy drop is dependent on the wall shear stress (τ) between the fluid and pipe surface. The shear stress of a flow is also dependent on whether the flow is turbulent

Objective: Motion on an Incline with Friction The purpose of this experiment is to prove that the experimental acceleration value calculated is close to the theoretical acceleration values by finding the tension force‚ normal force‚ kinetic friction and the coefficient of kinetic force from the data collected. Theory: The forces acted on an object can be divided up into many different components depending on what the object is doing. In this experiment‚ an object is sliding up an incline plane

Aim: The aim of this experiment is to test if the rougher surfaces produce more friction and affects the distance travelled of a toy car. The aim of this experiment is to determine if the surface areas affect the distance travelled of a toy car by creating friction between the surface and object. The aim of this experiment is to determine if the surface areas affect the distance of a toy car due to the force of friction between the two objects. Hypothesis: From the basic research shown‚ there
