Weighing half a credenza

[Lucky Dawg]

I know this is quite off topic...
My friend and I carried a credenza from my old office to my new one - he swears it weighs 500 lbs. Probably more like 250, but the beast was astonishingly unpleasant to carry either way.
My question: Can you weigh an object by putting one end of it on a scale (the other flat on the ground) and applying some physics multiplier to get an accurate weight? Let's call it 7 feet long - I would think the length would play into the calculation. (Also about 18 inches deep and hip tall, but I wouldn't think the latter measurements would be as relevant.) On my bathroom scale, one end of it weighs 147 lbs.

Can you tilt it up and balance it with one finger until the full weight is on the scale? That will give you its weight, +/- a finger...

If it is uniform, you can rest one end on the scale and with the other end at the same height, you'll have 1/2 the weight. If you hold it at an angle, the application of a bit of statics/trigonometrty will help get you closer to the actual weight.

If it is not uniform, then weigh both ends and add them-up... It will not be exact, but in the neighborhood.

- any of these methods should be as accurate enough for your bathroom scale experiment...


PS. If the bathroom scale is typically used for people, bring the scale out ouf the negative range where they typically sit and back to a 'Zero' starting point before using! :)

Ah, logic - make 'em the same height! The beast weighs in at 297 lbs. With one end on the floor, the other end on the scale weighs 147 lbs. With end number one on a 2x4, the weighed end tips the scale at 148.5. It weighed the same on both ends with my scale. Thanks!
