In a beam there are two point of contraflexures in a same segment . what kind of load is acting on that segment .
Answers
I WROTE THIS FROM A BOOK FROM THE LIBRARY OF MY COLLEGE IIT BOMBAY.
IF IT MATCHES UR ANSWER THEN ITS NICE .
A point of contraflexure is a point where the curvature of the beam changes sign. It is sometimes referred to as a point of inflexion and will be shown later to occur at the point, or points, on the beam where the B.M. is zero.
therefore, it is evident from the B.M. diagram that this point lies somewhere between C and D (B.M. at C is positive, B.M. at D is negative). If the required point is a distance x from C then at that point

answer : blending moment changes it's time
Explanation:
in the blending of beam, a point of contraflexure is a location where the bending motion is zero ( changes it's sign)
in a bending moment diagram it is the point at which..the bending moment curve intersects with zero lines
* at the point of contraflexure the bending moment is zero
