Project Finally Works!!

Failed twice the trials in my actual day(yesterday)...I was so damn frustrated!! Why our driven pendulum mechanism doesn't work?? So emo that time, almost scolded a friend, luckily today apologised to him... well, Dr Keith gave my group a last chance to fix the problem and run final test today. 71 oscillation in a minute...lowest expectation we had(suppose to get 80-130+)...but never mind, at least, better than failing the whole project...Thanks Dr.Keith!!
