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

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

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

bromide (polybrene) test in blood cross matching? Watch out! Abstract: BACKGROUND: Blood cross matching test mainly includes manual hexadimethrine bromide (polybrene) test (MPT) and the automatic analyzer method (by coombs card) at the Department of blood transfusion. Generally instrumental method is used for large quantities of samples. It can save manpower; MPT is used for emergency and few samples. it can save time. Our department recently encountered a case of cross match blood test by MPT was negative
