Question 1

The portal frame shown in the figure is subjected to a uniformly distributed vertical load w (per unit length). The bending moment in the beam at the joint ‘Q’ is

The bending moment in the beam at the joint ‘Q’ is

• Azero
• B (hogging)
• C(hogging)
• D (sagging)

Question 2

Two beams PQ (fixed at P and with a roller support at Q, as shown in Figure I, which allows vertical movement) and XZ (with a hinge at Y) are shown in the Figures I and II respectively. The spans of PQ and XZ are L and 2L respectively. Both the beams are under the action of uniformly distributed load (W) and have the same flexural stiffness, EI (where, E and I respectively denote modulus of elasticity and moment of inertia about axis of bending). Let the maximum deflection and maximum rotation be and respectively, in the case of beam PQ and the corresponding quantities for the beam XZ be and respectively.
