Rocky Marciano vs Tim Witherspoon.

Friction force is proportional with normal force and thus depends on mass, which means when two men are pushing each other, with all other things being equal such as the angle and friction cofficient, the one with bigger mass will push the smaller one.
Fact.

 

Best technique, huh how so, why are there weight divisions then?

 

You trying to say that Dempsey was as strong or stronger than Willard?

 

True.

False. The normal force is mass x acceleration and it's being pushed in the opposite direction that GRAVITY is pushing. You grossly misunderstand the friction-normal force equation.

When two men are pushing each other the force is going horizontal. Not vertical. Normal force requires a vertical force.

I can tell you recently looked this up today because you are misunderstanding basic physics concepts.

 

Weight divisions are determined by weight not by strength.

 

I’m saying he wasn’t being forced around in the clinch despite the weight disparity.

I don’t doubt that Willard was overall a stronger man, who could perform certain strongman feats better than Dempsey. But to Dagos point, there is an imbalance in the emphasis placed on size versus technique/mechanics.

 

But friction force is proportional to normal force, and the friction force is going horizontal and the guy with greater friction force will push the other one, so basically it depends on the mass.
I've been thinking about this for a while and came to this conclusion.

 

Which in most cases is proportional

 

Exactly. Most cases. This is one of those exceptions.

 

You're incredibly wrong. Do you understand what friction force is? It is a negative force that goes in the opposite direction. For example if you are driving north in a car there will always be a friction force going in the opposite direction slowing you down like air resistance (wind).

Your entire analysis is incorrect. In order for the bigger guy to move the smaller guy he would have to be exerting a force onto the smaller guy that is greater than the friction force and the force that the smaller guy is exerting upon him.

Do you also understand what proportional means? In this case the friction force is directly proportional to the normal force. In other words when the normal force goes up the friction force goes up.

The guy who's exerting more force than the other guy is (after taking into account friction for the other guy) after adding the friction force will push the other one. This brings us back to square one where the guy who is stronger will push the other guy.

 

You do not understand me, when i said proportional i meant in value not in direction.

Friction force is proportional to normal force in value(magnitude) but opposite in direction - friction force horizontal direction, normal force vertical direction.

And they both depend on mass, which is why i've been saying that they are proportional

Forces that two guys exert on each other don't matter cause of the Newton third law-action reaction, net force is the same but in opposite direction.

What matters is the Friction force and the heavier guy will have the greater one cause of his greater mass

If there is no friction, the smaller guy will again face a greater acceleration than the bigger guy cause of his lighter mass

Proportional doesn't refer to direction. I never said it did anyway. The normal force goes up. The opposite of up is not horizontal. The opposite of up is down. Of course they both depend on mass. ALL force depends on mass.

If you are saying they are proportional because they depend on mass then you are saying that ALL force is proportional because all forces depend on mass.

You're misinterpreting Newton's third law. Essentially what you are saying is that they are canceling out their own force then citing Newton's third law. This is incorrect. Do you honestly think that if someone has a mass .001 kg more than myself then they will always win? Regardless of who the person is?

Please, I don't need your link to dodgy physics forums. I learned in an actual classroom by a teacher with an actual degree. Clearly they don't know what they are talking about on there because all of your information is incorrect.

 

I know you are a kinda of hard to talk so I'll kinda stop this discussion.
The important thing is proven - greater mass pushes the lighter one - both in vacuum and with gravity and friction.

That's why a sumo wrestler will easily push George Foreman, and that's why a heavyweight boxer will always easily push a middleweight boxer.

You are probably underweight and thus think size doesn't matter, but it does I'm afraid.
Even women like the bigger ones

 

Here we go! You have no argument so you have to make up myths!

So are you stronger than everyone that weighs less than you?

 

No, but in the clinch size does matter - bodyweight.
For example, Holyfield probably could lift more weight in the gym than Bowe, but Bowe was still stronger in the clinch due to his bodyweight advantage.

That's why old Foreman was stronger in the clinch than his opponents, he had a big weight advantage.
