How heavy is a rock?

How heavy is heavy?

[bc47]

that is why I love the internet

It's nice to know we have a good split of Nerds and Comedians on the Ford Forum. Best laugh I've had for a while.


Cheers Vincenzo

It weighs more than the paper or scissors

or even a bodybuilders site that always seem to have some golden threads!

If the rock weighs more than an LS1 block, would that make it a more effective boat anchor?

What type os rock is it?



Representative densities for common rock-forming minerals (i.e., ρG) and rocks (i.e., ρB) are listed in the Table. The bulk densities for sedimentary rocks, which typically have variable porosity, are given as ranges of both dry ρB and (water-) saturated ρB. The pore-filling fluid is usually briny water, often indicative of the presence of seawater when the rock was being deposited or lithified. It should be noted that the bulk density is less than the grain density of the constituent mineral (or mineral assemblage), depending on the porosity. For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm3, with a porosity that can vary from low to more than 30 percent. The density of quartz itself is 2.65 g/cm3. If porosity were zero, the bulk density would equal the grain density.


Saturated bulk density is higher than dry bulk density, owing to the added presence of pore-filling fluid. The Table also lists representative values for density of seawater, oil, and methane gas at a subsurface condition—pressure of 200 bars (one bar = 0.987 atmosphere, or 29.53 inches of mercury) and a temperature of about 80° C (176° F).

Nah that's going overboard. He just needs to wet his hands, he'll be able to move it no dramas then

It wasn't a rock, it was a rock lobster

E=Mc2.........no rock, thereby no weight.

There's no more effective boat anchor than a VN V6.

What type of rock?

basalt.

By the way two of us moved it out of the way by rolling it under water.

Rock smashes scissors , paper covers rock.

Been a scuba diver for over 30yrs and can attest to it being heaps easier to move/lift heavy stuff underwater... And saltwater moreso (density)

[Charliewool]

Found some of my old notes...
Average rock in saltwater would be aprox. 2/3rds lighter.
So your 500kg rock would be 330kgs while submerged.

Next time the doctor asks how much I weigh I'll take the scales to the beach

[DJR David]

Yes but we all know that paper beats rock, so maybe you could use paper to move it?
