Note: A small amount of dish detergent was added to the water to help reduce the affects of surface tension. Students can use the associated activities to strengthen their understanding of relationships between the previous concepts and real-life examples. Fundamental definitions, equations, practice problems and engineering applications are supplied. This image shows a TA determining the actual number of pennies required to sink the block after the students have made their prediction. Students are introduced to Pascals law, Archimedes principle and Bernoullis principle. In this lab we will measure apparent weight of objects in different conditions to verify Archimedes’ Principle as well as use this principle to determine the density of solid and liquid samples. Part II requires the students to predict the minimum number of pennies required to sink a wooden block. In this image, the brass ring/tube is immersed in water while it is suspended from the triple beam balance by a thread.Īfter determining the volume of the brass ring/tube using Archimedes principle, the students confirm the volume by measuring the brass ring/tube with a Vernier Caliper. In order for something to stay afloat, this force must be equal in magnitude or in the case of lift with a hot-air balloon, greater than, the weight of the volume displaced by that object. air or water) experience an upward force known as buoyant force. Archimedes Principle is that an object totally or partially immersed in a fluid (liquid or gas) is buoyed (lifted) up by a force equal to the weight of the. Part I requires the students to determine the volume of a brass ring/tube using Archimedes Principle. Archimedes Principle states that objects in a specific medium (i.e. Notice: Printing in the Auburn University Physics Labs will result in your Bursar's Account being charged 50 cents ($0.50) per page Archimedes' Principle (Follow this link to print the Procedure/Data Sheet)
