1) The diameter of the aluminum cylinder is measured to be: (4.935±0.003)cm. The hanging mass (paint bucket and 5kg) for a Mechanical Equivalent of Heat experiment is recorded as (5.2977±0.0002)kg. The aluminum cylinder is turned 234 times. Calculate the work done cranking the aluminum cylinder.
2) The amass of the aluminum cylinder is (207.8±0.1)g. Once the cylinder is turned through the numbers of turns as described in Problem 1, the cylinder's change in temperature is (11.2±0.6)°C. Determine the amount of heat that entered the cylinder.
3) Based on the results of Problem 1 and Problem 2, determine the value for the Mechanical Equivalent of Heat as determined in the experiment described. How does this compare to the accepted value?
