A simple conclusion:-)

 

trees, waves and cakes!!:-)

I can understand points 2, 3, 4 and 5 but not 1!

 

Can someone please explain how a climber hanging from a single point can generate a force greater than his weight? (Assuming the climber is static)

 

I could be missing something but need help.

Basic up and down movement while climbing.

Thanks Kevin.

 

So the force, at particular points in time, can be up to 50% greater than the climber's weight.

Honestly I believe that it depends on how sloppy a climber you are. In this non scientific preliminary study, they used one climber going up and down the rope in a standard normal way. The drop tests were done in a tower.

Yes, I accept what you're saying.

 

My mistake, in reading, was to presume it meant that the climber exerted this constant force on the anchor point.

 

Thanks.

Interesting stuff Kevin, do you have an external link to this study?
