AI Thread Summary
Transporting three 1 lb iron balls across a bridge that can only support 200 lbs while weighing 198 lbs presents a challenge. The proposed solution of juggling the balls raises concerns about the downward pressure exerted during the act of juggling. It is suggested that tossing a ball high enough would indeed create more than 2 lbs of downward force. The consensus among participants is that the juggling method is not feasible under the weight restrictions. The discussion confirms that the original riddle's solution is flawed.

All,

A friend of mine recently posed the following riddle:

You weight 198 lbs, and need to transport three iron balls that weight 1 lb each across a bridge that can only support 200 lbs. How do you do it?

The proposed answer: Juggle the balls.

It would seem to me that tossing a 1 lb ball in the air high enough to juggle it would exert more than 2 lbs of downward pressure. What do you think? What would be the relevant equation?

Thanks!

No Fred, we've also answered this precise question a few dozen times as well...

The short answer, istock1, is that you are correct.

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
