All ISRO Mechanical & Aerospace papers | ISRO Mechanical & Aerospace 2008

Topic: Strength of Materials

The given figure shows the shear force diagram for the beam ABCD. Bending moment in the portion BC of the beam

Figure for question 76, ISRO Mechanical & Aerospace 2008

  • A. Is a non-zero constant
  • B. Is zero
  • C. Varies linearly from B to C
  • D. Varies parabolically from B to C

Answer: A. Is a non-zero constant

Explanation: If the shear force (SF = dM/dx) is zero in the portion BC, then the bending moment M must be a constant. Thus, it is a non-zero constant.
