By using titanium & aluminium alloy precision part which generally machined on 5 axis DMG mori CNC machines. By considering this amount of precision and quality control in manufacturing stage u can tradeoff FOS.
Spacecrafts perform in six Sigma level, so their accuracy is more and also fos depends on the materials. In space craft the materials used are aluminium composites and some parts are also made of titanium alloys which make them more stronger.
I don't understand why the calculation says that we should divide the UST by the working stress to obtain the safety of factor but then you actually: 450/3 arent we meant to find the safety of factor???
I have shown the formula of FOS in case it's not available & we need to calculate it. But for most of the designs, based upon the applications, FOS value has been recommended. I have provided some of those values at the end of the video as well. So, if you have FOS [Recommended] and if you know the working stress [By Design Requirement], you need to calculate stress to select the right material.
@@akashreddy3497 Yes, analysis, adherence to stringent regulatory guidelines and quality control measures are some of the ways they ensure safety even with the lower FOS;
FOS of aircrafts is low to ensure low weight for take off. Safety is ensured by strict safety and quality checking by in house and regulatory bodies.
100% correct answer :-)
Great Explanation sir...Thank you😊
Glad that you liked it 👍
Very nicely explained...Thank u so much
Thank you 🙏🙏
Kudos for ur explanation.... Grt job... Waiting for more videos....
Thank you Irfan!

Good answer;
Nice explanation sir.. Thank you..
Thank you Sampath!
Well put, I will never forget this
Glad you liked it :-)
In case of aerospace industry weight is dominating factory
So to reduce weight we choose low fos
Very nicely explained. Thank you
Glad that you liked it 🙏🙏

Doubt on max Yield stress, please recheck
Spacecrafts perform in six Sigma level, so their accuracy is more and also fos depends on the materials. In space craft the materials used are aluminium composites and some parts are also made of titanium alloys which make them more stronger.
So by using aluminium composites and titanium alloys they reduce weight of spacecraft with less fos also ensuring the strength of the craft.
👍👍
👍👍
in Space crafts -Reducing the Ultimate Factor of Safety below 1.5 will save a lot of weight.
Its a one time use that's why the FOS is low
Accuracy of prediction is high.

Hi,
music is a bit annoying.
Thank you Maris for the feedback! I will improve upon it in my next video!
To reduce weight aircraft industry uses low fos...
@@akashreddy3497 How they maintain safety then?
@@mechanicalvault they do analysis of material..
