Classic Part 2
If you remember from the last post, Indiana had to jump so he threw the idol and we showed with the math that it was less than likely. Now, interestingly enough right before switching the idol with a bag of sand at the beginning, removes sand to try and trick the trap. Based on the calculation from the last post and repeated again below, making the same assumptions the bag of sand would only weigh 4.41 lbs. You would think an archaeologist would know better when trying to trick a mass sensitive booby trap that gold and sand are very different.

I would be interested to know what type of device they were attempting to use for the trap. Being materials scientists, we know full-well that it is possible to make a switch that has such a high coefficient of friction upon releasing a load as heavy as gold that it would take time to depress the switch. But, what most viewers of the movie would think would be that as soon as a weight is removed, the switch is activated (similar to Entrapment).
ReplyDeleteI would also be interested to see a post this week about the movie Entrapment either calling the bluff on some of the technology they use or proving that it could work and Hollywood got it right for once. Some good research into lasers and suction cups could go into. Just a thought.
