A vertical load of 10 kN acts on a hinge located at a distance of L/4 from the roller support Q of a beam of length L (see figure).

The vertical reaction at support Q is

Concept:

Composite Beam is the one in which the beam is made up of two or more material and rigidly connected together in such a way that they behave as one piece. In the composite beam, there is a common neutral axis through the centroid of the equivalent homogeneous section.

While the compound beam is a beam of different element assembled together to form a single unit.

Calculation:

Bending moment at hinge = 0

Considering right hand side of hinge

Bending moment at hinge = 0 kN

R_Q × (L/4) = 0

R_Q  = 0 kN

∴ The vertical reaction at support Q is 0.0 KN
