1. Manager 2015 Paper 2 (Civil) · Q105 · Strength of Materials & Structural Analysis · Strength of Materials

   In a beam, where the variation of shear force is a second degree parabola and the variation of loading is ______, the variation of bending moment is ______.

   1. constant, cubic parabola
   2. linear, square parabola
   3. cubic parabola, square parabola
   4. linear, cubic parabola
   Show answer

   Answer: (4) linear, cubic parabola

   Since dV/dx = −w and dM/dx = V, a shear force varying as a second-degree parabola means the load varies linearly (one degree lower) and the bending moment varies as a cubic parabola (one degree higher).
