Hey all,
This is clearly a very simple question but for some reason my roommate and I just can't agree on this.
The scenario is as follows: There is a helicopter sitting on a scale. The helicopter weighs 700kg and thus has 700*g = 6867 N of force acting on it by gravity. In order to fly the helicopter must overcome its own weight and so it must produce >6867N of lift.
The question is, how much does the scale register on the millisecond the helicopter leaves the scale. My reasoning is that the scale must register 6868N atleast.
Please enlighten me.
