Friction Between Clothing & Giant Rock: 833 N & μ=4.58?

AI Thread Summary
The discussion centers on the feasibility of achieving a friction force of 833 N between clothing and a giant rock, with a coefficient of friction (μ) calculated at 4.58. Participants question whether this value is excessively high, noting that the coefficient of friction can exceed 1, making 4.58 theoretically possible. The scenario involves cartoon characters decelerating upon impact, leading to the derived values of mass and acceleration. While a μ of 4.58 is unusual for clothing against rock, it is not deemed impossible within the context of physics. The conversation highlights the often exaggerated portrayal of physics in cartoons.

Is it possible to have friction between clothing and a giant rock equal to 833 N? The μ would equal 4.58. Isn't it too big?
 
Physics news on Phys.org
Why would the coefficient of friction need to be 4.58? Wouldn't it depend on how hard they're pressed together?
 
Well this is for a physics project and a lot of it depends on guessing. We found friction to be 833 N, mass to be 85 kg, acceleration to be -2.14 m/s^2 because the cartoon characters are decelerating as they hit the wall. Will all of this μ(ma)= Friction, we found μ to be 4.58. We are just wondering if 4.58 would be too big for μ.
 
Oh, ok.

4.58 would be large but there's nothing in the laws of physics (as far as I know) that limits the coefficient of friction. I know at least that it can be greater than 1, so 4.58 isn't completely crazy.

Between clothing and a rock though, it would certainly be abnormal (but perhaps not impossible)
 
Everyone one knows that 'cartoon characters' always present physics in a true and accurate manner.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
