Does Wrapping a Whip More Times Increase Its Ability to Support Weight?

Click For Summary
SUMMARY

The discussion centers on the physics of a whip's ability to support weight when wrapped around a tree branch. It concludes that the friction force increases with the number of turns due to the relationship between tension and normal reaction. Specifically, the normal reaction is calculated as the number of turns multiplied by the tension in the whip. Therefore, more turns result in greater friction, enhancing the whip's capacity to support weight.

Currently I'm doing a physics project based on Indiana Jones. I was curious if the whip, when wrapped around a tree branch, can support a human weight. However I realize, depending on how many times the whip was wrapped around the branch, the friction force will increase. Yet based on the friction force, surface area is not taken into account and in this example, it should be considered. So how should I solve this?
Thanks

Hello Cellogirl! Welcome to PF!

in this case, there will be a tension throughout the whip. in ideal case the tension will be uniform. so friction force = Normal reaction x coefficient of friction.

here Normal reaction = no. of turns x tension in whip

so more turns implies more friction.
