Hi! why you use 238.6 for W than 490.5 ......... the value of 50x9.81 gravity g to calculate sigma s. Thanks in advance.

[@themechanicalengineer]

Its not the point load... It is the self weight of the shaft calculated using the density of the shaft... And that is considered as an uniformly distributed load ..

@@themechanicalengineer thanks a lot i understand your answer

[@Arunkumar-lh9ym]

@@themechanicalengineer When I calculate, the weight uniformly distributed is 358.18N. Can you check this.

[@themechanicalengineer]

Yes.... Its actually W=498.8 N/m...

[@herze1872]

Thank you so much s

[@themechanicalengineer]

Welcome!

[@mechanicaldivision4289]

Q5 weight is wrong..plz correct or comment plz

[@themechanicalengineer]

Which weight? In Question 5, the weights are calculated correctly.

[@themechanicalengineer]

Can you give me more details about your question??

@@themechanicalengineer Shared good problems thanks for that. The multiplication in the beggining while calculating W/N is its a mistake its a simple math do once.
