One member in particular: you.
Um, post #8: TENSION.
Post #10: TENSION.
You appear to have some difficulty in reading.
Word salad.
Nope.
That's why it's NOT a "centripetal force".
A ? of force.

Post #10: TENSION.
You appear to have some difficulty in reading.
Tension is the elastic bands action, not the reaction of the Melon to the action of the bands. Now you are trying to say that gravity is not an inwards direction on Earth/ You are quite mad.
Again that is not an answer to the question I asked, are you unable to read English and determine a question to be something else?Why are you here? It's obvious you have no tools other than you clueless fingers banging away at the keyboard.
Being an utter failure at critical thinking and having a childish tantrum when you're called on it just screams troll.
I am talking about Physical process of a displacement in dimensional space of the Melon by the force applied by the tension of the elastic bands , exerting a force onto the Melon.
Which part of the Physical process do you not understand?
Lol - says the guy who bungled the science in the first place!
The tension in the bands is hoop stress: http://en.wikipedia.org/wiki/Cylinder_stress
The inward force is just pressure.
Gravity is only a centripetal force if it is acting on a moving object.
Uh wrong.
The tension compresses the melon.
The REACTION of the melon is to "push back" against that compression (which, in the end is insufficient to prevent mechanical failure of the melon).
That is NOT what I'm saying.
Go back to school and learn how to read.
The tension compresses the melon, yes it put an inwards pressure on the Melons mechanics. Inwards to a center point that has nowhere to compress except upwards or downwards to the force that is isotropic circular inwards .
So if you are saying Inwards force in this instance is not centripetal, what are you going to call it, I call it centripetal pressure?
NO! The two have little in common.
I think you are thinking centrifugal or centrifical, rather than centripetal.
In reference to gravity as a centripetal force,
http://en.m.wikipedia.org/wiki/Centripetal_force
... gravity is considered to be a centripetal force ...
http://en.wikipedia.org/wiki/Centripetal_force
That is Centripetal Force:
The video shows zero centripetal force... period...
Actually it shows the effect that a centripetal force has on the velocity of an object.., which would otherwise follow a straight line... Should have read a little further in the Wiki article.Still the OP is as many have pointed out, almost laughable.., if it were not it seems.., intended to be serious!
If gravity was a force that only acts on a moving object, then that would not make sense to the mantle etc?
Thank you for at least agreeing with the gravity being classed has centripetal force, thank you. It may sound laughable, but if you consider density of mass having an applied pressure centripetal, the greater the mass, the more ''centripetal pressure'', is applied to the localised center of gravity.
While this is accurate,
The above is not as clear. Yes centripetal force is most often associated with its action on a moving object, but especially in the case of gravitation, the force remains even in the abscence of a moving object to act on.
I think the above is confused! I don't believe you can easily equate any presure associated with gravity, as a centripetal force! The pressure itself is not a force, in that case. It is the result of a force. Whether the force originates with rubber bands or gravitation.... Which have very little in common!
Nope.
Er yeah, let's look at the FULL quote "When a satellite is in orbit around a planet, gravity is considered to be a centripetal force..." I.e WHEN THERE IS MOTION gravity can be CONSIDERED to be a centripetal force.
It's NOT a centripetal force although in can be considered to be one. In fact the final part of that quote further invalidates theorist's claim "...in the case of eccentric orbits, the gravitational force is directed towards the focus, and not towards the instantaneous center of curvature"
Plus, as mentioned, there is no motion in the case of the melon.
I'd call what every engineer and scientist would call it: radial compression.
It doesn't matter what YOU f*cking call it.
It's NOT centripetal.
I do slightly disagree with you, inwards pressure, may be the result of a force, but when there is a solidity to consider, the force is changed into pressure rather than F=ma, because the mass has the inability to accelerate, it can only compress to a central point of an isotropic nature to pressure exerted by the force applied.
You consider that the ground pushes back and opposing an opposite force to the exerted force. This is not logically correct, all the molecules of the Melon for example on the circular plane of force applied, are trying to push inwards, and by direction can not oppose an opposing force to the bands, because the bands are the mechanism of direction of force. In the Melons instance, the resisting force to the melon imploding, is the resistance of mass North and South respectively to the circular East ,East, and West , West , joining of isotropic force, Centripetal to the center of mass force applied by exterior means.
"Melons mechanics" is word salad. You should have just said it puts an inwards pressure on the melon.
Pressure. Just pressure.
You are confusing how it is used or applied with its basic definition. Yes, how you are using the concept is how it is most often used... But that does not fully define it, only one application.
Centripetal force is defined as a center seeking force. Most of the confusion here probably comes from how it is used, in explanations of circular orbits or buckets swung round on a rope. Where it is a force in opposition to the (ficticiuos) centrifugal force and associated with a changing velocity associated with a curved path, like an orbit or buckets on a rope.
Gravitation is a center seeking force, where the center is defined by the center of mass involved. How it affects different kinds of orbits, depends on velocities relative to that, sometimes changing center of mass. But, in the case of gravitation, the center seeking force is present whether an object in motion is present to be acted on or not.
You are getting too many levels of forces involved! Next we will be talking about atomic and nuclear charges.
Gravity is a centripetal force and it does result in an increasing pressure toward the center of a gravitationally significant mass. But the pressure in that instance is not itself a centripetal force.
