Q1: The point of contraflexure is a point whereA shear force changes sign
B
bending moment changes sign
C shear force is maximum
D bending moment is maximum
ANS:B - bending moment changes sign In a bending beam, a point is known as a point of contraflexure if it is a location at which no bending occurs. In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line. In other words where the bending moment changes its sign from negative to positive or vice versa. |
