Rancang Bangun Rangkaian Timer Otomatis Pesawat Atwood
A research has been conducted on designing of an automatic atwood experiment
by using an automatic timer. The automatic timer consisted of three components,
four relays, one stopwatch, and one accelerometer. This automatic timer was used
to determine the duration time of the weight falling from a certain height. Testing
of the timer was performed on the atwood machine with four mass m1 and m2 that
are 0,2 kg and 0,22 kg; 0,19 kg and 0,23 kg; 0,18 kg and 0,24 kg; 0,17 kg and
0,25 kg. This experiment was done at height of 0,3 m, 0,4 m, 0,5 m, 0,6 m, 0,7 m,
and 0,8 m, respectively. The experiment results were compared to the results of
the same experiment but using a stopwatch instead of the automatic timer. Both of
the experiments, use the automatic timer and the stopwatch are compared to the
theoretical calculation. The results showed that the error percentage using the
automatic timer ranged from 0,82% to 5,42 %, while the error percentage using
stopwatch ranged from 5.96 % to 13,85%. It showed that the result using the
automatic timer gave lower percentage of error then the result using the
stopwatch.
