Strength of Materials | Module 5 | HOLLOW SHAFTS | (Lecture 52)

[@manjunathkodaramaiah6064]

God sent you for us🙂 Thank you so much sir Sir you will get recognition throughout India shortly.. Your awesome teacher...

[@vishalachari156]

I completed all the videos from this entire playlist. These videos have helped me a lot. Thank sir and Gate Academy Plus for providing this content.

No,it only consist pure twisting for applying a couples of force

[@sunilkumar-ln5eu]

sir,beautiful no words to explain the joy ur providing conceptual subject throughout ur lectures.. blessed

[@ananyamohanty3426]

sir, your lectures are very good. please upload further videos... we need you videos to study SOM in this lockdown. nothing else works.

[@dharamkarsainath49]

Good evening sir u r videos are amazing I watched all of them fm and td also thank you sir Sorry sir according to trescas theory of failure s*ys/ (2*FOS)

[@sonal6408]

Thanku sir..🙏

[@nitishsharma9107]

Sir, if Zp of hollow shaft is greater than Zp of solid shaft than solid shaft is stronger than hollow shaft as, strength is inversly proportional to Zp.

[@anjanikumarjha4778]

true. please correct if not so

[@anjanikumarjha4778]

EDIT : I just checked the Zs and Zh values by substituting the relations required ( D/D1 = (1-n^2)^1/2 and D2/D1=n) in order to verify it mathematically. I finally got the ratio Zh/Zs = (1-n^4)/(1-n^2)^3/2 and by comparing the graphs of both the functions in numerator and denominator, I found that (1-n^4) is always greater than the denominator term in the domain of n = 0 to 1. So, mathematically too Zh>Zs hence strength of solid > hollow if torque is same. I don't know why sir said it is the opposite.

[@divyarshpandey4791]

Yes it should be strength of solid shaft greater than hollow shaft in case same Twisting moment is given to both. I think what sir wished to inform us,is about Resisting Torque produced in both ,when tau max same for both(since both made up of same material).Resisting Torque=Tau max * Polar section modulus. Since (zp)hollow> zp solid Therefore Resisting Torque produced by hollow greater than solid.

[@anjanikumarjha4778]

@@divyarshpandey4791 Absolutely right. I learned this later on. The strength criterion of shaft is how much permissible torque (load) it can take. Therefore for same material (same tau), the one with higher section modulus is having having higher capacity of resisting torque.

[@rkg4626]

Same doubt here.

How its possible for equal weights for hollow and solid shafts????

[@guinslifecastle9037]

While taking the weight same and taking the relationship between the diameters, you have put the relationship in the equation considering same (tou max). How??

[@ajaypatel7966]

Sir material ko remove karake D1 ko badakar ham material ko save kaise kar sakte . Sir D1 ko badane se hamara material to badh rahaa naa

[@rajukhan2595]

Good doubt bro, Agr hm Diametere badate hai to hme torsional stress badega right! To isliye hm material remove krke diametere bada rahe hai jisse usefule material sare stress produce krne ke kaam me aajye *Conclusion* If we increase diametere then stress also increase

[@shubhamwr]

If weight of hollow and solid shafts are same, won't there be difference in weight density? How can shafts have same weight and same area still one has less material than other?

[@creativedebojit4606]

density is an intrinsic(or mass independent) property...it depends only on the material. Since the materials are same so densities will also be same.
