Question

the reaction at the roller supported end of beam is always​

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

REACTION AT ROLLER SUPPORTED END OF BEAM

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 response (R), and one moment reaction (M) (a) Hinge on the inside The bending moment at the internal hinge will be zero.

DETAILED EXPLANATION FOR ROLLER SUPPORTED END OF BEAM:

* When a beam rests on both ends on supports, it is referred to as a supported beam. The term "fixed beam" refers to a beam that is fastened between two supports.

* A pin-fixed support at one end and a pin-roller support at the other end should be used to support a simply-supported beam. The fixed end prevents the beam from moving freely along its longitudinal axis (no rigid body motion).
