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

The Charpy impact test‚ also known as the Charpy V-notch test‚ is a high strain-rate test which determines the amount of energy absorbed by a material during fracture. The Charpy test specimens were made according to the dimensions of standard ASTM A370. One of the main reasons for concern for natural composites laminates generally is the low values

To test the aptitude of the person‚ it requires manual dexterity whereby a joint in a person’s arm is controlled and predetermined stress in which the direction of the arm and the joint moves will lead to the deflection and it will be measured (Wagner‚ 1977). This experiment is widely known all over the world and it is usually used especially to capture the motor performance in a variety of situations. According to Bryden and Roy (2005)‚ they did the study to examine the influences of handedness

Lab: Energy Stored in Food Background Questions (5 points each = 10 points): 1. What happens to the molecules of the food that we eat during digestion? 2. What type of metabolism is this? Background information: In this lab we will attempt to set a variety of different types of food on fire and capture the heat energy that is given off. The heat energy from the burning comes form the energy stored in the chemical bonds of the food. The more energy in the bonds‚ the more heat the food will

no need for distillation. Next‚ a solubility test was given. When one drop of the unknown liquid was added to about 2 mL of water‚ the sample was tested to be soluble due to the dissolubility between the two compounds. By following the chart that was given on the sheet‚ the pH of the solution was tested. Since the two litmus did not changed color‚ the sample was identify to have a low molecular weight and a neutral substance. Based on the solubility test‚ some possible

Purpose In this lab‚ we used PCR and gel electrophoresis to identify genetically modified food. Introduction A genetically modified organism is an organism whose DNA or genetic makeup has been modified to code for certain desirable traits("Genetically Modified Foods"). Common genetically modified plants include corn and soy‚ and common genetically modified animals are fish. Many genetically modified plants are coded to resist bugs‚ grow faster‚ and produce bigger fruit‚ while most GMO animals

ups Identifying food groups in unknown solutions Aim The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added‚ some will change colour while others will separate. Introduction Food is a vital source of energy that is

The experiment was separated into four stages‚ the first being preparation of cell competency. In this stage two vials were placed in ice baths‚ one vial containing 50 µL of E. coli and the other containing a CaCl2 solution. 630 µL of the CaCl2 solution was then transferred to the E. coli vial‚ using a sterile pipet. After tapping the tube to mix the solution‚ it was then returned to the ice bath to continue incubation for at least 10 minutes. The cell competency preparation was carried out by the
