|Point of contraflexure is where BM changes its sign i.e from +to- or -to+.
S.F is maximum at that point.

|I was taught by my lecturer that the point of contraflexure is the point where the bending moment is zero. How true is that?|
|Mavish said: (Dec 18, 2014)|
|At contraflexure S.F is max so ultimately B.M is zero. And at this point B.M changes its sign means 1st it will reach 0 then change in sign occur.|
|Deepak Pathak said: (Aug 6, 2015)|
|Because if s.f=0. Maximum B.M will be their.|
|Emmanuel said: (Aug 29, 2015)|
|Were sagging B.M changes to hogging. That is from positive to negative or can be said to be point of zero shear force.|

|I think When SF change its sign at that point call a point of contraflexure. So at that time SF becomes zero and when SF becomes zero BM becomes maximum.|

|The point of contraflexure is mid point of beam where are bending moment are zero.|
|Belal Hossain said: (Mar 17, 2016)|
|The point of bending moment =0.|
|Mahesh said: (Jan 5, 2017)|
|Point of contraflexure is the point at which bending moment changes sign not the point at which bending moment is zero.
E.g. for a cantilever carrying a point load at its free end. BM at the free end is zero but no sign change ocure so it is not a point of contraflexure.
|Ashish Tadewar said: (Mar 15, 2017)|
|Shear force changes its sign and BM is max at the point of contra flexure.|
|Snehasis Samanta said: (Apr 18, 2017)|
|I think the correct answer is A.|
|Ms Ansari said: (Nov 13, 2017)|
|When the load coming change. It's which udl to point load because create point of contraflexure.|
|Jeet said: (Mar 8, 2018)|
|BM will be maximum when SF is zero, so I feel the correct option is B.|
|Munish said: (Mar 10, 2018)|
|Bm will be zero is called point of contraflexure.|
|Ankit said: (May 14, 2018)|
|Point of contrflexure is where sf changes it sign and there is maximum BM.|
|Tepal Siongh said: (Sep 24, 2018)|
|Point of contraflexure is maximum when bending moment changes its change.|
|Santhosh Kumar said: (Jul 23, 2019)|
|Point of contraflexure occurs where bending moment changes its sign from positive to negative or viceversa.|

|Abinab Ranjan said: (Sep 27, 2019)|
|Bending moment will be zero is called point of contraflexure.|
