Thread: Muscle Physiology Site

Thanks for the link DOMS.

The site covers a variety of topics and the information is presented well enough that you don't have to scratch your head to figure it all out.

You're welcome. I been referred to some great sites on IM (T-Nation, for example), so I thought I'd give back.

Nice....just saved it....nice work cfs3

No, that would be buoyancy.

If one places a copper ball in a pail of water it will sink, whereas a wooden ball will float. Whether or not a given object will sink or float in a fluid is determined by the buoyant force on the object. The buoyant force is essentially caused by the difference between the pressure at the top of the object, which pushes it downward, and the pressure at the bottom, which pushes it upward. Since the pressure at the bottom is always greater than at the top, every object submerged in a fluid necessarily feels an upward buoyant force. Of course, objects also feel a downward force due to gravity, and the difference between the gravitational force and buoyant force on a submerged object determines whether that object will sink, or rise to the surface. If the weight is greater than the buoyant force, the object sinks, and vice versa. It was Archimedes (supposedly while in his bath), who realized that submerged objects always displace fluid upwards (the level of water in the bathtub rose when Archimedes got in). Thus, he reasoned that the buoyant force on an object must be equal to the weight of fluid that object displaces. If the weight of an object is greater than the weight of displaced fluid, it will sink, wherease if the weight of the object is less than the weight of displaced fluid, it will rise. Moreover, it is evident that the volume of displaced fluid is precisely equal to the volume of the submerged part of the object, so that the difference between the buoyant force and the weight is determined by the relative density of the object and the fluid. In particular, we come to Archimide's principle, which implies that



This explains why wood and styrofoam float on water, whereas concrete and steel sink. It also explains why it is nonetheless possible to make boats out of steel or even concrete. As long as there are portions of the boat below the surface of the water that are hollow (i.e. contain air), the effective density of the boat can be less than that of water even though the real density of the material is greater.


Oops try again kid

Water doesn't float the boat. The buoyant force caused by the boat being on water is what floats the boat. Without buoyant force nothing floats.

Read the definition again dummy.

"Whether or not a given object will sink or float in a fluid is determined by the buoyant force on the object."

Keep reading dummy

Archimedes' principle

Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i.e., liquids and gases. It explains not only the buoyancy of ships and other vessels in water but also the rise of a balloon in the air and the apparent loss of weight of objects underwater. In determining whether a given body will float in a given fluid, both weight and volume must be considered; that is, the relative density, or weight per unit of volume, of the body compared to the fluid determines the buoyant force. If the body is less dense than the fluid, it will float or, in the case of a balloon, it will rise. If the body is denser than the fluid, it will sink. Relative density also determines the proportion of a floating body that will be submerged in a fluid. If the body is two thirds as dense as the fluid, then two thirds of its volume will be submerged, displacing in the process a volume of fluid whose weight is equal to the entire weight of the body. In the case of a submerged body, the apparent weight of the body is equal to its weight in air less the weight of an equal volume of fluid. The fluid most often encountered in applications of Archimedes' principle is water, and the specific gravity of a substance is a convenient measure of its relative density compared to water. In calculating the buoyant force on a body, however, one must also take into account the shape and position of the body. A steel rowboat placed on end into the water will sink because the density of steel is much greater than that of water. However, in its normal, keel-down position, the effective volume of the boat includes all the air inside it, so that its average density is then less than that of water, and as a result it will float.

And my Archimedes' principle is even spelled correctly.

If one places a copper ball in a pail of water it will sink, whereas a wooden ball will float. Whether or not a given object will sink or float in a fluid is determined by the buoyant force on the object. The buoyant force is essentially caused by the difference between the pressure at the top of the object, which pushes it downward, and the pressure at the bottom, which pushes it upward.

Of course, objects also feel a downward force due to gravity, and the difference between the gravitational force and buoyant force on a submerged object determines whether that object will sink, or rise to the surface. If the weight is greater than the buoyant force, the object sinks, and vice versa.

Your definition doesn't even spell Archimides' name correctly.

Can't help you with that, I didn't write it and I don't know who did.

Here are some other links with the same spelling........could be more than one way to spell it??? Personally I could care less, pointing out a spelling discrepancy is just a way to avoid the facts.

If they can't even spell the subjects name (there is only one way), how can you trust thier definition? It's the same reason that you shouldn't fill out a job application with crayon.

I listed five sites that spelled it wrong according to you......now prove to me without a doubt the proper spelling......and that their is only one way in the entire world to spell it.

The difference is "Jesse James" and "Jesse Jame". One was a natorious outlaw and the other wasn't. I'm not sure why you're so mistified how a single person's name can be spelled in only one way.

Sure, you could spell Bill Clinton's name as "Byll Clynton", but you'd only come away looking like a retard.

The style of the time (287-212 B.C.) in Greece was to have a name end in an 'S'.

Keep looking, I'm sure you will find a better argument than that silly post.
