Challenge Question #7:
"What percentage of a crane's weight is the transmitter?"
First, we have to figure out how much the crane weighs in grams. There
are 28 grams in one ounce. A pound would have 448 grams. So a crane that
weighs 22 pounds, would weigh 9856 grams.
A transmitter weighs 60 grams. That would be less than 1% of the crane's
weight.
I don't think they would notice it because it was not even 1%.
