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

AI Thread Summary
Wrapping a whip around a tree branch increases its ability to support weight due to the increased friction force generated by the tension in the whip. The friction force is calculated as the normal reaction multiplied by the coefficient of friction, where the normal reaction is influenced by the number of turns and the tension in the whip. More turns result in greater friction, enhancing the whip's load-bearing capacity. However, surface area also plays a role and should be considered in the analysis. Understanding these dynamics is crucial for solving the physics project effectively.

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.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
