Length valve is not given in this question. How you took? Explain me sir please.

[@motivationalwords1m193]

Yes broo....

[@akashkoiri2307]

sir by strength criteria the value of D=211.75 so you have wrote it 180 mm. And the length of hollow shaft is also not given

[@mufazzaljariwala220]

180 mm hi sahi hai

[@rajivkalia277]

What about length

[@mufazzaljariwala220]

@@rajivkalia277 vo question me diya rahega sir likhna bhul gaye honge

[@rahulmadane8807]

Excellent sir 👍

[@adithawidyaratne3499]

Sir are we supposed to calculate in both ways always and take the higher value or just one method is preferable?

[@wed-satanic6012]

No you must do both methods and obtain the higher result :)

[@adithawidyaratne3499]

@@wed-satanic6012 thanks 😊

[@yashdhotre7805]

Where is value of length given?

[@pravinbhaktebajajsteelimam425]

Sir, there is one question, how would we calculate angle of twist and safe stress of the material in practical aspect. Cause these are not known values in the material standard..? This is because I am facing difficulty while calculating design of shaft in practical aspect for a machine.

[@ChisomoLungu-sj2qo]

A steam engine cylinder has an effective diameter of 350mm and the maximum steam pressure acting on cylinder cover is 1.25N/mm Calculate the number and size of studs required to fix the cylinder cover, assuming the permissible stress in the stud is 33MP.. Take the thickness of the cylinder wall as 10mm. Assume coarse series with dc = 0.84d

[@yellowpotato5588]

Sir, where from you took the length of the shaft?

[@margebagra6260]

a hollow circular column having external diameter and internal diameter 30 cm and 25 cm carries a vertical load of 10 tonnes at the outer edge of the column calculate the maximum and minimum intensities of stress in the section

[@XYZ-hi9hk]

Sir , i have big confusion about unit conversion, Na and Nmm. Please sir , clear my confusion.

[@srikanthreddy7192]

where the length value given in this question...

[@GaneshShegar]

sir ..L ka value kaha se liya 2500

[@ammarahsansiddiqui8931]

design a shaft external diameter if the internal diameter to the external diameter is 3/8. take modulus of rigidity as 74 gpa and that hollow shaft is required to transmit 500 kw at 100 r.p.m., the maximum torque being 20% greater than the mean. Solve this question today is paper help me

[@amosemoz9296]

Please I'm having a question In Comparison the solid shaft would have shear stress..........that of the hollow shaft Please i wish to hear from you please

[@shaik_moizuddin8246]

Where did you took the length of the rod sirr ?

[@kaverim737]

Sir how get 5.85 sir plz simplify it clearly

[@nitinadhangle573]

Did you get it?

[@jahanvidewangan4350]

Sir, how length value is 2500??

[@AshokKumar-jf9km]

11:6 length how will you find

[@vinays961]

sir how you got d^3 from d^4-(.4d)^4/d

[@yash05195495]

vinay s its actually D^4-0.4D^4=0.6D^4/D He got it wrong i guess

[@viralxtweets]

he definitely got it wrong..

[@shivam.p2461]

So what should be the answer

[@SumanDas-ql1ue]

@@yash05195495 no bro (D⁴-d⁴) = {(D⁴)-(0.4D)⁴} [because d=0.4D] = 0.9744D⁴ And then calculation: 0.9744D⁴=836.86×10⁶ or, D⁴=858.8×10⁶ or, D=171.2 Sir ; your ans is right🙏🙏🙏

[@SatyamKashyap27]

D⁴ - d⁴/ D =1D⁴ - 0.4D⁴ / D =0.6D⁴ / D =0.6D³

[@Steerwithsvm]

sir the length value is not given in question ?

[@hritamsom6492]

length ki value kanha se aayi uddte hua?????????????????????????/

[@mithunbehera927]

Length value is not given sir how u take 2500 please give me reply please sir I have a confusion

[@tezrao3836]

Bhai Length kidar hai

[@ersavi4596]

Sir L ki value kha se ayi🤔

[@sushantborkar7870]

Rigidity ka nhi samja

[@sudiptaghosh2338]

where is the value of L????

[@victorsingh9712]

You r just copying dont even know that ur calculation is wrong.... value of D n d

[@kidsfun8219]

Length kha Se ai

[@motivational_thoughts6760]

Sir your answer eq 1 is wrong D=211.79

[@DineshKumar-bb3pc]

Correct

[@ajaydhawale6]

Are sir aap kisi bhi kimat ko nahi bata rahe aap apne likh rahe ho

[@vishnucharan4817]

Very Poor explaination

[@sagargangwani154]

your calculations seem to be wrong
