engineering recuitment GATE ME 2023-24 Test Series Strength of Materials Shear Force and Bending Moment Shear Force
Which of the following statements can be true about the shape of the elastic curve during the deflection of the beam?
1
If shear force is zero, the shape of the elastic curve can be a straight line
2
If shear force is zero, shape of the elastic curve can be circular arc
3
If bending moment is variable, shear force exists and shape of the elastic curve is parabolic
4
If bending moment is variable, shear force need not exists and shape of the elastic curve is parabolic.
