What is the output for my simple surveying calculations?

AI Thread Summary
The user is seeking assistance with basic surveying calculations, specifically regarding the output of a tension calculation. After performing the calculation, they initially obtained a result of 1.070181445X10^-9, which they were unsure how to interpret. Upon reevaluation, they realized that they should have used 28134 instead of 28.134, leading to a corrected output of 1.07 mm. The user expresses uncertainty about their understanding but feels they may have resolved the tension calculation issue. Clarity on the correct interpretation of the output is still sought.

Hi hope somebody can help

Have some simple calculations to do for surveying (see attachment) but not sure what the output is I am getting

Its not homework its practice really ...the formulas are given so its really just a matter of figuring out what the output is I guess not sure

Been 20 years since I've done maths anywhere near this so forgive me if this is simple for everyone

Trying to figure out the tension calculation for example

I do the following in calculator (65-50) x 28.134/1.905X2.07x10^11

The answer I get is

1.070181445X10^-9

But I have no idea what that means I am guessing its 1.07mm? Or have I done it all wrong
Can anybody help?

I think I may have figured it out for tension at least

Should have put 28134 rather than 28.134 so that does come out as 1.07 mm

I THINK :)
 

Thread 'Non-orthogonal bases'

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...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

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...
