For a beam in pure bending, the shear force along its length is

  • A.Maximum at the ends
  • B.Zero
  • C.Constant and non-zero
  • D.Equal to the bending moment

Answer: B

Pure bending means the moment is constant, and since shear force is the rate of change of bending moment along the beam, it vanishes. The condition is convenient in theory and is approached in a four-point bending test between the loading points.
