Mathemat >>:

Вы хотите сказать, что, измеряя периоды колебаний (пружинных весов или маятника), Вы добьетесь более высокой точности?

No... what we mean to say is that it said "acceptable measuring instruments - clocks and scales". And the paper could have been in diamonds.

You said it was a piece of checkered paper.

I would still find out in this story on what planet and in what system this is all happening. It could be in Betelgeuse, near a binary star, on a passing asteroid. :)

 
Swetten >>:

Я бы в этой истории ещё выяснила, на какой планете и в какой системе всё это происходит. А то вдруг где-нибудь в Бетельгейзе, возле двойной звезды, на каком-нибудь спутнике. :)

What a fantasy.

 

You have to keep your eyes and ears open for him. You've got to keep your ears open. :)


And fantasies, that's for ace.

 

It's not about volume. There's the weight and there's the mass of the weight. The pendulum doesn't care about weight, but the scale does.

That's how you calculate volume.

 

Approximately 1-2% error in length can be achieved by measuring the oscillation frequency of a pendulum with a conventional stopwatch

It is possible to count quite a number of oscillations.

Also, the smaller the swing, the greater the accuracy

 

About the coded sheet

Excessive amounts of background data may be entered deliberately.

The composition of the subjects could have been broader to be confusing.

It's an experience I've had since then.

 

Once again, for those who don't understand.

You use a pendulum to calculate mass. Without the pendulum you calculate the weight. And you don't need any cells.

 

Richie, did you study physics at school - or did you take a walk? How is it that a pendulum doesn't care about weight? And do you remember the formula for the period of vibration of a pendulum?

2 Ais: OK, we are making a scale of lengths. With the accuracy of a spring scale on the order of 'half a kilo left - half a kilo right', this scale will be much coarser than a cell on paper. Also, where do you get the different masses to calibrate from?

And again: with this scale, how do you measure the sectional radius of a weight (if it is cylindrical)?

 
Richie >>:

Ещё раз повторяю, кто не понял.

По маятнику вычисляете массу. Без маятника вычисляете вес. И никакие клетки вам не нужны.

Well then, what is the density of the weights, answer already?
