LAB B
Experiment 7B: Archimedes’ Principle and the Buoyant Force
Scenario/Summary
The purpose of this exercise is to measure the buoyant force on and the volume of water displaced by a submerged hanging mass. By varying the volume of the mass you will verify Archimedes’ Principle.

Introduction
An object that is submerged in a fluid will displace its own volume of the fluid. Archimedes’ principle states that the displaced volume of fluid exerts a buoyant force on the object that is equal to the weight of the displaced fluid. In this experiment a hanging mass (see the figures) is suspended from a force sensor by a string. The apparent weight of the mass is measured before and after it is completely submerged in a glass graduated cylinder that has been filled with approximately 40 mL of water. The displaced volume is measured by comparing the water levels before and after the hanging mass is submerged. The buoyant force is measured by the difference in the apparent weigh of the mass before and after it is submerged. The measurement is repeated for total masses ranging from 0.400 kg to 0.100 kg. A graph of the buoyant force versus the
displaced volume can be fit to a straight line. The slope of the straight line should be equal to the density of water times the acceleration due to gravity.
This exercise is different from the other labs in this course. The experiment has been done for you. You will analyze the data.
