- Calculate the average and error as for table 5. Compare thisnumber to your adjusted torque due to weight in data table4.
- Are they the same within experimental error. If not, whatother sources of experimental error may exist that you arenot accounting for? If you had to do the experiment allover again, what would you do differently to obtain results thatare more accurate?
