How strong am I? - SV650.org

Or equally, how knackered and broken am I?

Today I excavated 25 square metres of wet mud down to a distance of 5 inches.

I then stuck it in buckets and a wheel barrow and carried it 10 metres and up 6ft of steps to dump it.

So who can reliably estimate how much 25 sq metres of wet mud/ 5 inches deep weighs and how do you work it out? (for the young'uns 5 inches is about 12cm).

If it was a pond, you'd be looking at 2,500 litres of water
3 cubic metres

And I believe 1 cubic metre of water is approximately 1 metric ton, so assuming mud is maybe 25% heavier than water by volume (total guess), 3.75 tons was shifted by your knackered, broken self.

As i order ton bags of stuff fairly regular...

I metric ton of building sand or sharp sand equates to approx 0.6 cubic metres in real terms.

Knowing wet mud is quite dense, im estimating around 4 tons in weight, no biggy

not very strong and not very smart either

I have put all the elements of this equation into a super computer that was built by Stephen Hawking and Carol Vorderman so it's the tits.
The results are as follows

Total weight moved = 9.3 Dawn Frenchs
Total amount of beers earned = 5 pints or 7 cans
Brownie points earned from wife = 0.125
Total amount of impressed Orgers = you

ha ha I'll have to remeasure then, cos there is no way I could have done 5 metric tons (3/0.6) in one day.

Mind you it felt like 5 tons, 10 hours of dig, hump and lump. I could barely open a bottle or two of beer at the end of it

Edit: Shaddup Winder ya funny fecker numpty.

DP. No can do, garden has no access, for diggers. I could have hired some ukrainian diggers but I is too tight to pay £2/hr.

by my reckoning you have dug the equivalent of a grave. that's bloody good going.

25m^2 x 0.127m = 3.175m^3 as previously mentioned. (5inches x25.4mm = 127mm)

Standard bulk density for partially saturated soil = 18kN/m^3

18kN/m^3 x 3,175m^3 = 57.15kN

57.15kN x 1000 / 9.81 = 5825Kg or about 5.8T

Edit: does seem alot by hand in a day.... you sure it was about 5m x 5m on plan? And thats probably a bit of a conservative estimate. 18kN/m^3 could easily become 19 or 20 depending on they type of soil.

actually...

Tonne bags as they used to be known only hold 800 kilos these days.
Hence the change of name to "bulk bags"
