Question

The number of reaction components at a roller is/ ar

Answer 1

Answer:

At roller support there can be only one externally independent reaction which is normal to the contact surface. At guided roller supports there can be two reactions: (i) one vertical reaction (R) (ii) one moment reaction (M.) (a) Internal Hinge At internal hinge bending moment will be zero.

Answer 2

The number of reaction:

Explanation:

• There can only be one externally independent response at the roller support, and it must be normal to the contact surface.
• There are two possible reactions when using guided roller supports: One vertical reaction (R), and one moment reaction (M) (a) Hinge on the inside The bending moment at the internal hinge will be zero.
• Fixed-support: At the point where it is joined to the structure, a permanent support restricts any movements and rotations.
• There are six support responses applied from the support to the structure since the joint with fixed support has no degrees of freedom.
• There are two possible reactions when using guided roller supports: One vertical reaction (R), and one moment reaction (M) (a) Hinge on the inside The bending moment at the internal hinge will be zero.
