AI Thread Summary
To calculate the length of the side of a roof on a scaled-down model, the original dimensions must be converted to the same unit. The real house has a central support pole height of 10 meters and a roof side length of 14.67 meters. When scaling down to a model with a pole height of 20 cm, the scaling factor is 1/50. Therefore, the side length of the roof on the model would be approximately 29.34 cm after conversion and scaling. This method ensures accurate representation in the model.

Hi guys,

I need to figure out the length of the side of a roof on a scaled down model.

The picture below shows what I’m trying to calculate. The real house has a central support pole and it is 10 metres high, with length of the side of the roof at 14.67… metres.

If I was to make a scaled down model of this house where the central support pole is 20 cm, how would I calculate the side roof on the model?

As they say a picture tells a thousand words so I drew one up:

I have no idea how to calculate that length so if anyone can shed some light I’d be most grateful :cool:

Cheers!

10m = 1000cm. Notice that 1000/50 = 20, so the scaling factor is 1/50.

So what would the length have to be on your scale diagram?
 
Hi ProveIt.

Many thanks for your helpful reply :D

Ok so given what you pointed out, I would say that I need to convert the length in meters to centimeters and then divide by 50, which would give the model length to be around 29.34cm?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
