Chee Yong Hui 6.5 Domino Effect IA Investigate the effect of the distance between each domino on the time taken for all the dominoes to fall Independent Variable: Distance‚ d/cm‚ between each domino. The distance d/cm is measured between the middle of one domino to the middle of the next domino Dependent Variable: Time taken for all the dominoes to be toppled to the ground. The timing will start when the 1st domino is hit by a metal ball and it will stop when the last domino falls completely

Objective The purpose of the Jominy test in this experiment is to determine the hardenability of three types of steels‚ namely EN 8‚ EN 16 and EN 24. Introduction This report will try to illustrate how the hardenability of these types of steels vary and why. This will be done by using the Jominy end quench test on each of the test pieces and then testing the hardness of the particular steel from the quenched end‚ to the end of the test piece. Taking these different points will enable me to find

Purpose: To practice direct and indirect measurement Introduction: Do you think you could measure the average thickness of a sample of M&Ms without directly measuring selected M&Ms? The answer is "yes‚" and in this activity you will make direct and indirect measurements of the thickness of M&Ms. You will compare the results and evaluate the reliability of each method of measurement. Be sure to view the tutorial on the proper use of the vernier caliper. Please re-visit the information on when

Hurricane Katrina was one of the strongest storms to impact the coast of the United States during the last 100 years. Hurricanes all start in tropical waters because they can only start in warm waters. The wind and air conditions must be just right‚ and once a hurricane is started it can be moved around by powerful winds. They are basically a very deadly cyclone of wind and water. They range from category 1 to category 5‚ with 5 being the worst. The most deadly hurricane was on September 8th‚ 1900

Work Measurement on Katsa Bag Production (Gifts and Graces: Cainta‚ Rizal) I. Rationale Environmental issues and problems started to arise last decade. Awareness and drive to solve these problems has grown to 89% (NIHERST‚ 2008) since 2008. This has resulted to different campaigns and movements such as the Earth Hour Campaign‚ where everyone is encouraged to switch off household lights for an hour and the birth of eco-friendly products into the market. One of the most in demand and popular

Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp‚ thus becoming a projectile with a horizontal initial velocity. We measured the horizontal initial velocity using the photogate and computer. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure Experimental Set-Up In our experiment‚ we used the following:

Title JOMINY END-QUENCH TEST Objective To determine the hardenability of plain carbon steel. Theory Hardenability is the ability of a steel to be hardened and form martensite during quenching. Hardenability indicates the depth of hardness which is obtained from quenching process‚ and it is very important to the components of machine especially tool steel. One of the methods to determine the hardenability of steels is Jominy End-Quench Test. Hardening usually involves quenching

ABSTRACT This document describes the experimental process of developing a non-mechanical hot plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration
