Answer / bhoopendra

at that point
bending moment
change its sign.

Answer / ganesh kulkarni

point of contraflecture means the point where its sign
changes from +ve to -ve or -ve to +ve with respect to base
line.

Answer / mukesh biswas

The point,where the bending moment value is zero,that is known as CONTRAFLEXTURE point.INn this point the bending moment change it's sign means -ve to +ve or +ve to -ve.

Answer / ajay partap singh

point of contraflexure is a point where bending moment changes sign in bending moment diagram. On the one side of this point there is sagging and on other side there is hogging or vice versa. This helps to find out where reinforcement should be changed. As on one side sagging means tension is on lower side so reinforcement is on lower side and on other side hogging means tension on upper side so reinforcemrnt is on above side. So significance is that bending moment is in opposite directon hence position of reinforcement can be precisiley determined.

Answer / somesh mathur

Point of Contraflexure is simply the point where the bending moment diagram changes sign and as a result the radius of curvature changes sign. It has nothing to do with shear force at the point. At the point of contraflexure bending moment is zero but vice versa may not be true.

Answer / state

its the point where shear force changes its sign...at this point the bending moment is zero.....

Answer / mohammad aasif bhat

Point of contraflucture is a point where the value of bending
moment changes from positive to nagative and the value of shear
force is high.

Answer / meraj ahmad

point of contraflexure is a point where bending moment is zero(0) or bending moment changes its sign.

Answer / shankar

whenever change in bending moment sign negative to positive or positive to negative that point is called contraflexure.this point shear force is zero.

Answer / suresh baria

Point of Contraflecture is a point where bending moment &
shear force both are Zero
