clearly presented are carried out in the Civil Engineering department soils and materials labs at AUB. Finally‚ an analysis of the results and possible improvement methods and precautions to avoid polishing of asphalt pavements are proposed. Introduction During the entire life cycle of a pavement‚ highway agencies are expected to monitor and maintain an adequate surface roughness to facilitate friction between car tires and pavement surface. Polishing is a smooth slippery surface

Lab 4: Newton’s Second Law Lea Finocchi September 24‚ 2013 Partners: Amanda Okeefe‚ Sara Rojek‚ Kiran Kandola Objective: The objective of the first part of the experiment was to derive an expression‚ under conditions with negligible friction‚ for the acceleration of a cart on a level track when it is attached by a string to a hanging mass at the end of the track. With the value of acceleration and the mass of the weight divided by the mass of the weight plus the mass

Part one: The Lab 1. You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same‚ or different‚ rates in the air and in a vacuum. Before you conduct your experiment‚ you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your hypothesis

Four holes were drilled on the shoebox with electric drill. (Larger than the axles to reduce friction from the cardboard on the axles) 4. A hole was drilled near the top of each pole. 5. The box was cut on the two sides and the poles were inserted and taped onto the cart. 6. The string was wrapped around the back axle. 7. A CD was attached on
