Experiment 4: Friction Laboratory Report Anna Rucelli Ignacio Michael Giorgio Lapus Ted William Lardizabal Janell Leica Lee Department of Occupational Therapy College of Reabilitation Sciences‚ University of Santo Tomas España‚ Manila Philippines Abstract The experiment verifies the laws of friction with the use of a spring scale‚ a block of wood‚ its different surfaces and the different surfaces of other objects. Another part of the experiment uses the palms of the hands to produce

experiment is to study the friction loss along a pipe. In this experiment‚ water and mercury have been used to demonstrate the law of resistance with different types of flow which are laminar and turbulent flow. The variation of head loss will be obtained and hence determined the Reynold numbers and friction factor. In the end of the experiment‚ the law of resistance which is the relationship between i and u will be determined and hence established the critical R and friction factor. 1.0 Introduction

Static Friction INTRODUCTION When an object is placed on a surface it will remain static unless the resolved component of the force due to gravity acting parallel to the surface exceeds the friction force associated with the static coefficient of friction between surfaces by placing various objects on a surface and tilting the surface until the object begins to slip. By measuring the angle at which the object begins to slip‚ it is then possible to calculate the coefficient of friction between

Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. It would also help in pipe

Collazo 1 Asia Lee Collazo English Comp. I Professor J. Mohan February 14‚ 2013 “False Appearance’s” We are confronted with many different images of others. These false images can either be externally imposed or internally fabricated. In either case‚ one must have the courage to look through this ignorance so that ones true self can be exposed. After reading Mirrors it was obvious that‚ Lucy Grealy cared what others thought about her physical appearance. In time‚ however

Buoyant Forces The purpose of this lab is to calculate buoyant forces of objects submerged in water. The first step in the lab was to measure the mass of a metal cylinder‚ which was found to be 100g‚ and then to calculated it’s weight‚ which was .98 newtons. Then next step was to measure the apparent weight of the cylinder when it is completely submerged in a bath of water using the formula Wa=ma*g ‚ this was found to be 88.5grams. Knowing these two numbers‚ the buoyant force that the water
Premium Force Density Fundamental physics concepts
a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. Measurement of the fluid flow‚ often must understand its flow‚ flow rate distribution. Reynolds number is the characterization of fluid flow characteristics of an important parameter. Fluid flow when the inertial force F g and viscous forces (the friction) F m ratio known as the Reynolds number. OBJECTIVES

The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side guide block and setting it aside
