load test Aim: To determine the strength characteristics of a rock using the point load test and visual judgement. Materials Loading device Loading frame Pump Ram Platens Rock Caliper Method (Standard‚ 2007) 1. Measure the dimensions of the rock which includes the diameter and length 2. Find the length to diameter ratio to determine which test will be used. If the ratio is greater than 1 use diametrical test. But if the ratio is between 0.6 and 1 use axial test 3. The axial test was

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:

3. LABORATORY TESTS USED TO STUDY THE STRENGTH OF CALCARENITES There are 3 distinct methods or tests used to determine the strength of calcarenite which are needle penetration test‚ unconfined compression test‚ and direct shear box test. 3.1. Needle penetration test This form of test is done on site on an outcrop rock that is not disturbed; this is usually done by extracting a sample material for oncoming laboratory work. The penetration tests are done on two different sections of outcrop with an
