Date: 09-02-2013 Experiment 1(a) Laboratory determination of water (moisture) content of a soil sample by oven drying method Reference: ASTM D2216-98 Need and scope of the experiment: In almost all soil tests natural moisture content of the soil is to be determined. The knowledge of the natural moisture content is essential in all studies of soil mechanics. To sight a few‚ natural moisture content is used in determining the bearing capacity and settlement. The natural moisture content will

The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

1. The Little Albert Experiment - 1920 The Little Albert Experiment was conducted and published in 1920. This experiment happened at Johns Hopkins University by John B. Watson and Rosalie Rayner. The study was conducted to prove that there was evidence of classical conditioning in humans making them fear things‚ such as white mice‚ by the unconditioned fear of loud noises. Watson felt that fear was learned and that children were not born with it‚ and he wanted to find support for that. He believed

Balloon Car Experiment Newton’s First Law of Motion states that when an object is set in motion‚ it will remain in motion until acted on by an outside force. Theoretically‚ this could mean you could travel at the same speed forever in one direction‚ right? The reason we don’t see this happen is because of friction. The force of friction is the resistance to motion that is in the opposite direction of the traveling object. This is why if you roll a ball on the ground it eventually stops. Friction

The ball mill is mainly used to grind materials in mineral‚ cement‚ refractory‚ chemical industry‚ etc. Ball Mill has dry and wet ways. When wet Ball Mill works‚ certain water and other liquid will be added into materials to increase flowability of materials‚ so the capacity is increased. When dry Ball Mill works‚ capacity is affected because material flowability is reduced‚ so absorbing wind device is needed on the outlet of Ball Mill‚ and then negative pressure is formed in the Ball Mill to increase

Objective The objective of this experiment is to compare the theoretical internal moment with the measured bending moment for a beam under various loads. Introduction and Background Theory Definition of a Beam Members that are slender and support loadings that are applied perpendicular to their longitudinal axis are called beams. Beams are important structural and mechanical elements in engineering. Beams are in general‚ long straight bars having a constant cross-sectional area‚ often classified

"Her First Ball" is a title which itself suggests anticipation‚ excitement‚ fun; it is all that and more for Leila. Through the absent narrative‚ she is presented to us as a simple‚ innocent shy country girl who is yet to experience something fun and grand‚ like this ball. In fact‚ this ball itself is used as a metaphor for her own life; her transition from the innocent youth to the mature adult. We see this as the story progresses‚ and through her actions we recognize her thoughts. At the beginning
