Analytical Balance for Indirect Measurement of Mass

Analytical Balance for indirect measurement of mass

Analytical Balance for indirect measurement of mass

Here is instructions for an experiment to indirectly measure the mass of a bolt.  There is a whodunit element to the exercise in that the instructions do not give clear directions as how to go about measuring the mass since the bolt is attached to a nut that cannot be removed. A number of hints are provided in the copy and also suggestions on determining the mass using a balance beam or an analytical balance.  The choice of method and equipment to use is largely left to the discretion of the student with only the goals being stated and a few focus questions being asked to help establish the direction in which to move the experiment.  Give it a try and pop your answer in the comments below.
