sir in underbalanced section the maximum strain in concrete is not going to be 0.0035 but still why are we using the same compressive force formula of 0.36Fck b Xu
It is because the under-reinforced, balanced, and the over-reinforced sections when solved from the limit state method of collapse in flexure the 5 assumptions comes in to play when designing a beam. One of the assumptions is that the maximum value of strain a concrete can take before showing prominent and visible cracks is 0.0035 (obtained from extensive testing and analysis). These assumptions are covered in lec. 2
Why we put C = T when it's limiting stage as in limiting stage C and T will me on their limiting or maximum value then how can be both of them are equal?
Mst👍
🙏🙏🙏👌👌🙏
Incredible
Thanku so much sir please make long video sir
Thank you sir
Very good question...
@GATEACADEMY, SIR The value of Q may be differnt for 0.48 times depth of neutral axis. # Curiosity.
Thanku sir

Sir this formula is valid for balanced section but without checking the section how we can directly apply this formula here.
Please make long vedio

Sir, please solve the problem of o/r section
Please upload Environmental Engineering lecture
Sir which *Calculator* do you use???
Itna easy nhi ata sir..
2007 me Aya tha
Thank you sir
