Say you have a 12 foot log that weighs 150lbs and is being supported by 8 men who are spaced 1 1/2 feet apart from each other, how much weight is each man supporting?

>> No.1533599

please help

>> No.1533610

150 divided by 8 = 18.75

>> No.1533616

>>1533610

You're retarded. You have to multiply it by how far apart they are

150lb 12' log?

What the fuck?

Is it fucking balsa wood?

And why the holy hell would you need 8 men to carry it?

>> No.1533618

are the men 1.5 feet apart from shoulder to shoulder or from center of mass to center of mass

>> No.1533624

how much should a 12ft log weigh? i have no idea

>> No.1533635

>>1533617
log pt, navy and army do it

>>1533618
center mass

>> No.1533636

don't think you have to calculate the space because they all would carry the same weight in the end.. amirite.? if not oh well

>> No.1533642

If its as that as the one in the picture, probably 500stone

>> No.1533652

OP then answer is 18lbs give or take a few

I'm guessing at best 600-800lb for a 12' log of average density, assuming the diameter is similar to that of the ones in the picture.

500 STONE?!

more like 11 stone

the logs they weigh are 150lbs we have one in our rotc, they are telephone polls

>> No.1533665

it depends on how much force each man is using, there could be n lazy fuck who is crouching a bit.

>The caber toss is a traditional Scottish athletic event practised at the Scottish Highland Games involving the tossing of a large wooden pole called a caber, similar to a telephone pole or power pole. It is said to have developed from the need to toss logs across narrow chasms to cross them. In Scotland the caber is usually made from a Larch pine tree.
>similar to a telephone pole or power pole
>A caber typically is 19'6" tall and weighs 175 pounds.

500 stone what are you retarded? A 12-foot log TWICE the thickness of a typical caber would be like 30 stone (~40lb), and that's generously huge.

Here's an example about supports.

Adding more supports won't change the principle so feel free to study it.
